How did the wasp do it?

[Bill in NC]

Worst was when I pushed a running lawnmower over a bare patch of earth that contained a yellow jacket nest.

Took awhile for my brain to register the consequences, i.e. "why all of a sudden are hot needles being driven into my thighs?"

Once I got back into the car I pulled up my shorts and watched one sting, then walk a little bit on my skin, then sting again...took lots of Benadryl that day...
