Wow! Thanks for the hilarious and informative responses! I was so excited to get out there and find a treasure that I went ahead and purchased a unit today. Last night I found out a little more about using the Pocket PC and decided that it just might not last so long out on the trail. I really appreciate the info., however, and the laughs as well!!! Speaking of rental cars... I recall about 21 years ago, my dad, some friends, & I were hunting in S. Texas, and had rented a Station Wagon. We were amazed at how this thing was drinking gas (we thought). Turns out we'd put a hole in the gas tank while going over some pretty rough terrain (I can see them now- those sandy, rough trails, with very "high" centers!). And I don't know where we found it, but we used some sort of sticky, gum-like substance, to patch the tank. And Dad probably "forgot" to mention this incident to the rental co. when returning the wagon!
