We go geocaching! Usually when we go on a trip we will get some caches. It's a great excuse for a hike or just a way to visit somewhere. We've found them on college campus', parking lots, intersections, hikes, beaches, city parks and foreign countries. Truly, they are everywhere! We like to sneak in caches when we have some time to "kill." My daughter plays a lot of soccer so at her away games we'll download some local caches while she's warming up, find them and return for the start of the game.
For even more educational aspects there are puzzle caches where you have to solve a puzzle to get the coordinates. Or multi-stage where you have to find one cache, get the coordinates for the next caches, find the next cache and so on. There is one cache around here that they keep stocked with stuffed animals for kids when they find it! We don't collect coins but we do help caches that are traveling, i.e. travel bugs.
My husband is the techie expert. He learned that for some city caches you can find them just by putting the coordinates into google maps. Get the coordiantes off geocaching.com. My husband has an iphone and really you need a GPS even with an iphone for the ones out in the country and woods. It is much more accurate. He has a Garmin etrex Venture HC. It seems to do really well. I suggest trying some caches using google maps or borrow a GPS and see how much you like geocaching before investing in the GPS.
We started due to DH's parents who are big cachers. They are retired now and spend a some of their time together going for caches.
Unfortunately, my daughters are not big cachers. They whine but then they actually enjoy looking once we are there. But that's them. I took my daughter's Girl Scout troop caching and they all enjoyed it.
The dark side to it: it can be a real time killer looking for a caching, reading about it, etc.
