I have pulled alot of this ivy plant from a retaining wall behind my house. It is among some (I believe) english ivy. I am located in southwestern Pennsylvania. I have never developed a rash, but I'm not sure if that's just by luck (never looked for/avoided poison ivy), or that I just don't react to the oil. The one picture is from a section of a hill behind my house, which I'm pretty sure is poison ivy. Does poison ivy only have big broad leaves as depicted in this picture? Any feedback would be greatly appreciated. Thanks
