In a post I wrote last year, I mentioned Geocaching. The ChiTown Cachers is a local group of cachers who organize events and get togethers to share stories of geocaching and to gush over their GPS units (I'm presuming). Most importantly, there's a huge list of caches all over the Chicagoland area. For even more info, join the Yahoo Group. Damn, do I want a GPS unit now. Another item added to the summer To Do list.
