I always have one with me. I'm one of those unlucky folks that could get lost in my own yard, in view of my house. ;D I hunt deer and elk in a national forest 200 miles from home and with my former hunt crew did not get to learn much of the mountain and valley we "hunted." Now, with the confidence my GPS has given me, and with a good compass and map, I find that I am more likely to explore and have learned much in the last two years about this area. I have also used it to mark good watching areas on heavily used game trails, likely spots for bow-hunting, and to mark trails I would like to visit with my atv. When my kids start hunting with their friends, rest assured I'll have provided them with GPS devices as well.
