Once when I was on a river trip, one of those black and yellow fuzzy bees was flying around. I swung at it with my paddle and it came back after me and flew up my SHORTS and stung me twice before I was able to beat it to death inside my pants...
Just a mental picture for you all of a 6'2 wet woman trying to run a rapid while jumping around fighting a ferocious bee, who will NEVER swing at one of those again...
