I, too, have done the Yellow Jacket Two-Step... I was 8 years old, and stepped on a nest. I got stung over 100 times, that's when the nurses quit counting. I was quite a ways from the house, it was over an hour before I got back, and about another 45 mins to the hospital. As we got into the ER, my breathing stopped from my reaction. Needless to say I was very lucky...
I was in the ICU for 48 hrs, then in a reg room for another 5 days for observation, thank God dad had excellent health insurance! Had to carry an epi-pen for years after that, tho I haven't had a reaction in about 10 years now.
The worst stings are those white-faced hornets... I'm 6'7", 325# or so, and those lil buggerswill drop me to my knees...
if you have a few minutes, do a Google on Japanese Giant Hornets, absolutely amazing
