My behavior begged for poison ivy irritation. There were several 15 foot vines of PI in a fairly tight area. They were creeping up some big cottonwood trees. I was shirtless, and was bending over to grab and twist the base of the PI stems with a Vice-Grip (smart, eh?)...So my back definitely came in contact with some of the ivy.
What do I do with the vice-grips now? Just wash in soapy water? They've been bouncing around the floor of my truck for a few days now with that oil on them.
