I'm sitting here, right now, with the complete side of my right knee covered in pi rash. To tell you the truth, I'm used to getting attacks every now and then, but I try to avoid them. This time we were doing fire prevention clearing above a city hiking trail. PI was everywhere but I was careful. I think what happened was I came home, stripped in the garage, brushed my pants against my knee and the stage was set. It really sucks because I have big bottles of anti-PI lotions, pre-exposure stuff, wipes, etc. I just wasn't careful enough after I got home. Damn urushiol! Benadryl lotion lets me sleep at night, and I slap it on before work, too. Climbed all morning, today, in 90 degree weather. Never scratched, once.
