FYI this is what poison ivy looks like. It has 5 leaves and red tinges in places. It is an invasive vine like other ivies, morning glories, honeysuckle, etc. Some people are very sensitive to it, others (like myself) not affected at all. Poison Sumac is another one that does affect me but it looks different, smaller, less leaves, leaves are more curved. There is a new app you can download where you photograph a plant and it identifies it. Might be helpful to some of you who don't know plants, I've found it very interesting and educational.
