Yes I do. A guy who used to be a long time regular at DCHS, Arizona Mike some years ago for a time owned property near ours up in Northern Cal. One day when he was up there and clearing part of his land he chopped a bunch of " bushes " along the ground, gathered them up and burned them. He tended the fire as it burnt to make sure it was controlled and breathed the smoke at times while he was moving around the fire. Those bushes turned out to be poisen oak. He had a horrible time of excrutiating pain for weeks so bad that he said he would cry at night and he also had to go to the hospital since he had also inhaled the smoke from the burning poisen ivy, as well as what he got all over him since he was carrying the stuff to the pile too. Man, what a bummer :-(
