I am afraid of lightning, falling out of my tree stand, snakes, and bees/wasps/hornets. I try very hard to get out of the woods quickly if a storm is brewing. I always use a safety harness in the tree, except for one stand that is so low, that I will hit the ground before the safety webbing engages, so I am not sure quite what to do other than be very careful. Now, I wear snakeboots regularly. I try to watch out for stinging things, particulary yellow jackets and hornet nests, but these seem to be hard to see at times.
