Yet another hobby?

I've known about Geocaching for a while now and have quietly looked into it from a distance.  Then was somewhat introduced to it last June at the Varsity Big Event, only it was on a very small scale.  Ever since then I've been quite interested in purchasing a handheld GPS (I already own a unit for my vehicle) and giving it a try. Earlier this month at roundtable we had a guest speaker come and speak about it a bit and so my interest has becom even more intense.  Combine that with some points that I've collected on one of my credit cards (thank you mega-summer 2008 family vacation) and I was able to pick up a basically free (I think that I paid $20) handheld Magellan GPS unit. I'm excited, hopefully I'll lose a few pounds, get in better shape, and have some fun while doing it. So now I'm all set, except for the time to go and actually do it.  I wonder if I can get some of that with the remaining points on my card too.
