Nothing dramatically scary like some of y'all.
Only time I've been really, um, unhappy with a situation hunting was when a buddy and I walked into one of his uncle's raggedy plywood shooting houses early one morning near the beginning of the season. We weren't seriously hunting - just hanging out and drinking coffee while waiting to see if any meat walked in front of us.
As it got light, we could see 2 or 3 big old red wasp nests in the nooks and crannies of the boards holding the thing together. Maybe 30 big wasps and us in that little bitty room up on stilts. We carefully retreated and hoofed it on back to the house....
