Bee in my bonnet

Sunday while riding along the boardwalk to the Huntington Beach Pier, I had a bee fly into my helmet.  Before I realized what was happening, he stung me on the forehead.  I got my helmet off and swiped the bee away, but the damage was done.  I had almost reached where Karen was walking when stung, so I was able to stop and have Karen pull the stinger out.  I guess I'm not allergic as I didn't swell up or pass out.

I rode my bike thru a swarm of bees once, but was able to ride with one hand and swat the bees away with the other.  I wonder if my bright yellow jersey has anything to do with it?
