The last time I got stung while riding was probably 2007. Bee hit me in the groin area during a high speed decent. Just missed my man parts.
But...Back in September I was taking a lunch break in a park during a tour across PA. I had an Odwalla smoothie drink open on the ground. Went to take another sip and ended up spitting out a bee. I think it had drowned, but I did get pricked on the tongue by its stinger. Only slight pain and a minor numbness for maybe 15 minutes. I dodged a bullet.
