The bastards! I was with tradhead and got stung 7-8 times in a matter of seconds. Never saw the nest, or the wasps themselves for that matter, I was running and yelling in pain, hopefully not girly yells. Also a bit allergic, I was swollen for a few days. Now I will bring some benadryl when I go climbing so if I get stung I can decrease the swelling as well as take a nice nap while on belay duty.
