Editing 2931: Chasing

The least chasable are stationary places like the {{w|Grand Canyon}} or {{w|International Date Line}}. It makes no sense to chase them because they don't move around, you simply go to their known locations. At the other end of the chasability spectrum are animals that move around rapidly, and fleeting astronomical and atmospherical phenomena like {{w|clouds}}, {{w|meteors}} and {{w|aurora}}. However, some of these are difficult to chase because they're small and hard to detect from a moving vehicle, e.g. {{w|gnats}}.

In the top-right position of most chasable and most exciting, tornadoes have a community of 'chasers' who attempt to predict their appearance and get as close to them as possible, which was the subject of a {{w|Twister_(1996_film)|1996 film}}, for which a sequel was due to be released shortly after this comic. A major {{w|Tornado_outbreak_of_May_6%E2%80%9310,_2024|tornado outbreak}} had also taken place immediately preceding the comic's publication.

| {{w|Niagara Falls}} || 15% || 75% || A generally stationary place on the border of US and Canada, between the state of New York and the province of Ontario. The waterfall is the largest in North America by width and water volume, making it very beautiful to watch.

| {{w|Tourist attractions}} || 15% || 55% || Other stationary places that attract many tourists (e.g. national parks, monuments and historic places) are exciting to see.

| {{w|Hazard (golf)#Bunker|Sand trap}} || 15% || 25% || Pits of sand in golf courses. If your golf ball lands in one, it loses all its momentum almost instantly and it is difficult to hit out to the grassy portions (fairways or greens), which is why it is a "trap". A convoy of golf-carts might "chase" a golf-ball to the sand trap it lands in, but this would not be very exciting.

| The International Date Line || 15% || 10% || A jagged conceptual line running from the North to South poles around 180 degrees of longitude, used to separate the time zones that start and end each day. There's nothing to see at these locations, as the line is an abstraction and does not actually coincide with anything in real life, as well as mostly being in the Pacific Ocean, by-passing actual landfall, as well as across the Arctic Southern Oceans. The zones for {{w|time in Antarctica}} are already more pragmatically simplified or just fall back to {{w|Coordinated Universal Time}}.

| {{w|Comets}} || 40% || 85% || Comets are chunks of rock and ice that orbit the Sun, usually in highly eccentric orbits that take them from the inner Solar System to the {{w|Kuiper Belt}} or {{w|Oort Cloud}} at the extreme outskirts of the Solar System. Few of them are visible to the naked eye until they are close to the Sun. They're exciting to see because they are rare, and one of the few astronomical objects that looks like more than just a tiny dot because there is a glowing "tail". While they are moving very rapidly through the Solar System, from the Earth they don't appear to move much faster than planets. So there's no need to chase them; when near the Earth, they will be visible from much of the planet for days or weeks.

| {{w|The Moon}} || 40% || 70% || Earth's only natural satellite with a predictable orbit. While Randall is most likely referring to chasing the Moon on the Earth, the {{w|Apollo Missions}} very much fit the description of "chase in a convoy of vehicles coordinating over radio and using instruments and data to find optimal viewing locations". That is exactly what the astronauts did, they "chased" the Moon (the Moon was moving while they flew towards it) using a convoy of vehicles (the multi-stage rockets) while they "coordinated" to Earth with their radios. Only 12 people (the {{w|Apollo astronauts}}) have actually visited it in person; the rest of us see it from about 250,000 miles (400,000 km) away. Weather permitting, it's visible for about half of every day/night cycle (though may be more obvious when this occurs significantly in the night sky, for several reasons). It doesn't move quickly in the sky, by apparent movement, so little chasing is necessary. A 'supermoon' is when the Moon looks the largest and shiniest, occurring when a full moon appears closest to the Earth in its orbit, though Randall doesn't consider this phenomenon impressive (How To, chapter 21).

| Unusual clouds || 40% || 55% || Clouds with unique forms or shapes, like {{w|Lenticular clouds}}. People may want to chase after them if they’re drifting away, as they may want to view the cloud further, perhaps for scientific purposes.

| Regular clouds || 35% || 40% || Clouds are an aerosol consisting of a visible mass of miniature liquid droplets. People may chase clouds for the same reasons as wanting to chase unusual clouds.

| Aurora || 60% || 95% || Impressive light displays that result from excitement of the Earth's {{w|magnetosphere}} by charged particles in the {{w|solar wind}}. These are generally only visible in high latitudes, so most people do not live where they're visible. Their visibility can be tracked and forecasted via monitoring of solar wind output from the Sun, and particularly intense episodes can be predicted (as well as locations for viewing) on the basis of the solar cycle and solar flare activity. The release of this comic coincided with the strongest geomagnetic storm warning forecasted by the National Oceanographic and Atmospheric Administration (NOAA) in 20 years [https://www.swpc.noaa.gov/news/g4-watch-effect-may-11] ({{w|May 2024 solar storms}}).

| {{w|Tumbleweed|Tumbleweeds}} || 60% || 15% || A roughly spherical portion of certain plants that breaks off from its roots and rolls along the ground, propelled by winds, to distribute the seeds of the parent plant. Most people don't find them very interesting to look at, and they're often used as a shorthand for nothing of interest happening. They don't usually travel very quickly, so it would be possible to chase them if you were so inclined. The locomotion of tumbleweeds is of interest to ecologists, as the non-native and extremely invasive plant disperses its seeds across a region.

| {{w|Speed_limit_enforcement|Speed traps}} || 65% || 5% || A section of a road where police often wait for passing drivers who are exceeding the speed limit, so they can catch them and issue speeding tickets. Frequent drivers, especially truck drivers, have developed systems to warn each other of these locations ({{w|citizens band radio}} was once the most popular method, but now this can be done using mobile phone using services like {{w|Waze}}).

| {{w|Tornadoes}} || 85% || 95% || Wanting to witness a tornado is the typical objective of {{w|storm chaser}}s.

| {{w|Whales}} || 85% || 90% || Widely distributed and diverse group of marine mammals. They are some of the largest animals to ever live, and often travel in groups, making them exciting and easy to see (when active at the surface). They have often been chased by humans, both for the purposes of hunting and exploiting them as a resource and by tourist-oriented whale-watching trips.

| Other chasers || 90% || 10% || May result in an awkward or friendly encounter if met in person. Chasers may bond over their enjoyment of chasing various objects, much like how [[Geohashing|geohashers]] connect with each other at specific geohashed locations. However, another group of chasers might not appreciate it if they find out that they're being the target themselves.
