Poison Ivy Everywhere! I tried to to on a nice hike this afternoon at Hartwood Acres with my pup and I ended up covered in poison ivy. It was hanging over the trails and, in some parts (trail 18), the trail went right through a field of poison ivy. I've never seen so much at one time. Needless to say that after washing myself and my dog in dish soap, I have decide that we are never going hiking there again. Beware!
