I got stung in the leg by a bee last year over on Santa Fe Dam, thankfully it stung me on my thigh through my shorts so the stinger didn't even really stick in me at all! Lucked out on that one, just a sharp pain and a tiny little bit of swelling, probably partially because I got the stinger out in a few seconds.
I didn't see any bees on GMR today either. Two weeks ago there was one that would not leave me alone when I stopped at the flat above the shack before the short descent to the Y junction. I was really in need of a bit of a break, and that bee was just harassing the heck out of me! Jerk.
