A few weeks ago, when I asked about an altimeter, 4 or 5 of you suggested (some strongly) that I get a GPS. Well, after some more thought, I bought the cheapest you can get (as far as I know), a Garmin Etrex, at Walmart last week. Honestly, I didn't have high expectations for the thing, but figured if I could at least mark some key locations (i.e., the truck, camp, and a kill site), I may have a bit more peace of mind. I have to say that after just two short scouting trips, I am sold and don't want to go back to being without it! The etrex does more than I expected, and is a cinch to learn to use. Thanks to all who contributed the good advice!
