Back in the day, I used satellites to find Tupperware in the woods. It was called geocaching.
Basically, you get a GPS unit and go to the Geocaching website. (No, you don’t need the GPS to get to the website. Just a browser. And a computer or mobile device.) Satellites in orbit around the Earth send signals that help you pinpoint a location and an approximate route to it. (They’re not dedicated geocaching satellites, of course. They perform some other function like mapping or spying.)
When you go to geocaching.com, you enter the zipcode of where you live or are traveling to, and it will tell you whether there are geocaches in that area and where they are. The trick is, you only get latitude and longitude coordinates.
You make your way to the site, which usually involves car travel and some walking, through city streets or neighborhoods or woods or swamps or off overpasses or in parking lots. When you reach the destination, you find…something.
And what is the cache? Well, it can be a Tupperware container or an ammo box or a film canister or a pickle jar or anything waterproof. Depending on the size of the container, there may be trinkets inside. The rule is take one, leave one. There is also a sheet of paper where you list your name and the date you found the cache. Then you return to the website and log that you found the cache – or how many times you tried and failed.
What makes any of this fun? You get to feel clever if you find the cache. You get out in the fresh air and walk around, while still avoiding other people. And you get to rack up points on the website boasting of the number of caches you’ve found. You can geocache alone, with a partner, or even a group.
What types of geocaches have I found?
First, there are the regular caches – the ones I mentioned that come in Tupperware and ammo boxes. These are usually relatively easy to find, located in hollow trees, dense brush, and once under an overpass. That one I missed at first, but a moment later realized where it had to be. I used the excuse of accidentally dropping my keys over the railing as an excuse to go back for it, so that no one would question why I was rooting around down there.
Another popular cache is the mini-cache. These are the ones that come in small containers. The smallest mini-cache I ever saw was a mouthwash-strips container that held only a log for leaving your name. That one was in a shrubbery in the median of a residential street.
Then there’s the micro-cache. These are so small that no trinkets can possibly fit within – just the log. I once found one of these logs wrapped around a 10-penny nail loosely stuck in a fence post.
Hide-in-plain-sight caches are often attached with magnets to some metal thing at the destination, such as an industrial station near a street or highway, or a lighting fixture in a parking lot. The back of the magnet or a strip of paper hidden behind it is where you leave your name.
Photo caches. For these caches, you take a picture of the location that corresponds to the coordinates – usually a scenic or historic building. You don’t post the picture on the GPS website, just the fact that you found it and the date.
Foreign caches. When my husband and I vacationed in Eastern Europe, we took along the coordinates of some caches there and we brought some trinkets to leave. One cache we absolutely knew the location of, but were unable to get to because a pile of snow intervened.
Puzzle caches. These may involve solving a code to get the coordinates or knowing (or looking up) the answer to a clue. Some are even more elaborate. One I remember was an acrostic made from the names of a series of books.
Wheelchair-accessible caches. There aren’t a lot of these, but they do remind us that the pastime isn’t just for the able-bodied.
Dan and I haven’t geocached lately, but our days of indulging may not be over. We intend to place a geocache in a nearby park. Will we use Tupperware? Maybe, but more likely a film canister with a scroll log and a pencil stub.
Too bad our GPS unit is as ancient as we are. We could also relive our glory days of hunting and finding.
