I hunt alone and am getting up in years so I carry my cell phone to the stand each time. When deer are in my stand area at dark and I can't come down yet, I phone my wife and let her know I'm ok and am just letting the deer feed out of my area before coming down from my stand. It's a safety thing and also reassures my wife that I'm ok. Before cell phones, she'd worry herself to death sometimes. LOL. Oh, and it has come in very handy this season to call my friend and son to come and help me get those two big bucks out I have gotten so far this year.
