I got stung about 20 times in the lower leg/s one time as a teenager. I was doing a job where I had to cross a narrow bridge several times, that happened to have some yellowjackets buzzing around it that day. I had an injury at the time that prevented me from running, so I had to just walk through (actually I tried sort of using the bridge handrails like crutches to move faster) and deal with it. It wasn’t that bad.
I assumed they were yellowjackets, at least, because they were yellow and I don’t recall them leaving stingers in me.
A month or so ago, I was cleaning the gutters on my carport. I discovered during this process that the cheap gutter covers the previous owner had installed were much more effective at keeping water out of the gutters than anything else, so I decided to just pull them all off. I got to the last one, slid it off and discovered a large yellow-jacket nest. Fortunately, they didn’t notice me, and I managed to get the thing back on before they attacked. Unfortunately, the ladder was up against that section of gutter, and I had to figure out how to manipulate it to a new spot and get down, which is not that easy to do from the roof.
I haven’t been stung by any kind of wasp since I was probably 12 or so. I got a single bee sting when I was about 20, and nothing since then (I’m 33). I’m really fine with keeping that streak going.
