I got lost once in 4500 acres of state land. Lets just say I never want to do that again. Fortunately, my hunting buddies heard my yelling and saw my flashlight, so I was only lost for a few hours.
The real scary part was, it was the night before rifle season opened, and I was wearing only camo clothing, as I was bow hunting. I would've hated to have to have spent the night in there, only to wake up knowing that there were rifle hunters in there and me not wearing any orange. I think we all know that there are some crazy people out there that will shoot at anything!!
Needless to say, I now have a GPS, and won't go into the woods without it, and a compass as back up...no matter how well I know the land.
