Hi C.,
A friend of mine told me about Geocaching and after reading a little more about it (www.geocaching.com) I bought a GPS device—handheld—and my 2 teenaged boys and I started Geocaching. It's kind of like a treasure hunt and it got us out of the house, cooperating for a common goal (to find the cache) and it was just fun. It also took us to some previously unknown and/or unappreciated areas around Champaign-Urbana. Not only was it fun to hunt for the caches, but it was great seeing new things and areas in this city that we thought we knew so well. The biggest expense was the GPS unit, but you can find them on e-bay, or if you know someone who has one, maybe you could just borrow it now and then.
Good luck!
