I've been lucky to be able to hunt private land, but I too carry a cell phone with me when I'm out. Mainly for emergencies, *amn near fell out of a tree once and realized my cell phone was back in my truck. Not a great feeling when you think you're about to fall, probably get hurt, and don't have anyway to get ahold of anyone. I keep it on vibrate so I don't spook the deer. It would kind of tick me off if that happened to me though.[:@]
