FYI...Poison Ivy

I was checking out the Empress of Dirt and she wanted to know about a plant before she started getting rid of it. I , as fast as I could type, said NOOOOOO, DON'T TOUCH IT! I searched for a web site that had pictures so I could learn the difference between poison ivy, poison oak, and poison sumac...I would post pictures of Emmy, Bryce and I but there might be a definate revolt.
