My three young children pick the berries on this plant near the driveway before we realized that it must be poison ivy or something similar. Please confirm what it is. It must be particularly strong since our reactions have been so severe. I'm sending several pictures. The plant came from three main stems (fuzzy) growing up a dead tree in the back of this growth. I filled 3 large yard bags with just this one location. We live in NW Atlanta in an old part of town that has some natural buffers between houses.
