Is this poison ivy in Wisconsin backyard? I think so but I'm second guessing because its common here and I often peel the vines of these things off the wall bare-handed to get rid of them, but I don't get a skin reaction. I just recently thought wait... three leaves, spikes edges, could it be? Thank you for the help! Originally by u/valentina-black on Reddit: https://tinyurl.com/2a9cktzd
