Dear all, just writing one last note about the poison ivy discussion. When I sent the first letter regarding prevention of poison ivy, it was not for my own benefit. I was just getting some info on it for my friends, who often hike in the woods with me during land-snail collecting, and have gotten it quite badly before. I myself am immune to it, a trait I got from my father. I have often been hired to get rid of the stuff, which I pull up with my hands. I just wanted to inform everyone who was in on this discussion. Kindest Regards, James
