Never seen one in PA. Years ago, when I was a kid growing up in Monroe, CT, I did. Was walking in a field near abandoned rail road tracks with my trusty Crossman BB gun, when I seen what I thought was a woodchuck. Don't know why, but at about 30 foot away, I decided to shoot it.
So I did. It wasn't no woodchuck. When I hit it, it growled, and immediately started chasing me. I ran like only a scared 9 year old kid could, and got away. Later we looked up in a wildlife picture book what it could have been, and yep, it was a badger.
