pashnit if you had been allergic to bees you would have died from that sting.
I've never had that issue with bee stings, had my share through the years while riding. And no, not allergic to anything. Another time got one in the back of the neck while leading another tour. Wasn't sure how he was able to fly that fast & catch up to me!
I had to read up on that level of swelling later on -evidently when you are stung on the top half of your head, all the blood vessels in your upper face carry the venom better. Bottom half of your head - chin for example - not so bad. But getting me in the temple - obviously exactly where the bee would go when you flip up the visor - was the worst possible place to get stung from the standpoint of human anatomy & where the venom goes.
One of the fellas on that tour was indeed allergic , and his last sting had sent him to the emergency room so he watched over me pretty closely. We were in a really remote area of NorCal so likely 2 hrs from closest hospital. (if someone crashes badly, we need a helicopter).
But overall, that was first. We're talking 25+ yrs & 200,000+ miles of riding & that's never happened before.
