Don't group them all just because of this guy. The one I have in the picture I caught while they there fishing Sat. evening. This little kid got my line 3 times, I let him reel it over and he freed it. When I got my fish on, one guy walked out and cased over my line (witch would have ended the same as your sons fish). He didn't know I had a fish on, when he cased over me I told him he cased over me and I have a fish on. He said sorry and worked his line off of mine and they all stayed out of the water until my fish finely left the hole. BTW, up river at the Gard rail hole a white guy was fishing from the other side, any body in there right mine wouldn't be fishing there, he would case over every body's line and F it all up. He was a real a--hole.
