Bumble-bee at 80 mph dead center in the chest.
Thought I’d been shot.
I took a bee in the neck at 40 mph, which hurt for a bit, and then hurt like he** when he survived the impact and stung me. :)
June bug to the neck at over 70. Same reaction.
Also, got caught in the rain with just a tee shirt. Even at below the speed limit, when I got home, my arms and neck looked like I had massive sunburn. It hurt.
An owl or some other night flying bird hit me one early evening south of Iowa City. I didn’t go off the bike but came very close...
