25 miles into a 30, I caught a bee in me bonnet while ripping down a hill at about 30 mph. It stung me, and stung me, and stung me some more until I could get stopped and rip my helmet off. I may have squealed like a little girl.
At least it finally happened. I KNEW it would.... now it did. Got a nice lump on my head, but I didn't lose control of the bike and resisted the urge to tear my own fool head off at speed.
