Photo: Diane Edwardson, October 1, 2009. Poison Oak (Toxicodendron diversilobum) on the 18-Acre Parcel of Elysian Park between Riverside Drive and Landa. (Click on photo to enlarge.)I received a correction to Saturday's post on Poison Oak from Poisonivyguy regarding the spread of the rash once you've contracted dermatitis from Poison Oak. You cannot spread the rash once you've washed the resin off your skin. Rather than paraphrase the lengthy explanation and risk getting it wrong again, see the following links and learn more about it.

Wiki: Urushiol-induced contact dermatitis
