Can You Identify Poison Ivy, Poison Oak, & Poison Sumac?

I have a greatnephew, one of the sweetest kids you'd ever want to meet, who is EXTREMELY sensitive to poison plants. He barely needs to be down-wind from the stuff and he becomes polluted. Now others of us may not get as bad a case of the contact dermatitis as he does, BUT we ALL should be able to recognize the culprit. Tracy @ unlessthelord has provided an excellent tutorial on what these plants look like. Thought it might be of interest to others.

Y Blessings,
