Your story reminds me of a bee incident many years ago that involved a helmet and a bike -- though the bike involved was a motorcycle. DH & I went on a motorcycle trip for our honeymoon. We were riding though the mountains in North Carolina when I say something come at me and then felt a sting -- a bee had flown up under my helmet and stung me on the forehead. I started yelling at DH to stop the bike, we took the helmet off and saw I had a wopper of a sting. Ouch!
