You have permission to use this picture. I took it in my back yard on June 19,2003. This plant is growing on a sand dune just at the back of my lawn. I will have children over for the holidays and want to be sure this is not poison ivy. I am located in Muskegon Michigan, on the west coast of the state on Lake Michigan. Please let me know if you need more information or additional photos. Thank You! Rob Schweifler
