My husband read about geocaching somewhere on the internet just over a year ago, and decided we all need one, so he bought 3 eTrexs for Christmas, knowing everyone would want their own to look at.
It's been a great 3 season family activity [too hot and humid in the summer to do much outside, unless it's out of state]. It's been such fun, I just bought a new GPS: an M330, and can't wait to try the mapping features.
