Garmin Get BackSomeone also sells a 3 or 5 spot GPS gadget that is about the size of a silver dollar and has a save button - that'll get you back to the truck at the end of the day. Forget what they are called but I want to get one for hunting and fishing where I don't want to mess with the full size GPS... Like tracking deer in an area I hunt all the time - nice to go back to the road where you went in.
