Also add to that the fact that you could be wrong too and send yourself in the wrong direction. When the wife and I go out, she has a Garmin forerunner attached to her bike and i have the paper maps. paper maps are also could if you want to connect to another trail that probably won't show up on the GPS map. also paper maps are great when the gps battery dies, or for some reason, known or not, it can't reach it's satellite. however, if you take many wrong turns and get totally lost, the GPS helps a lot more than the map.
