Just fyi - I submitted a request to the company that makes Pokemon Go, to attempt to get the game out of the south part of this park. Someone in our group came close to hitting a girl just wandering in the woods playing that game (along with a dozen other kids we saw). Who knows if the request will just get ignored, but thought I would at least try. Someone could get seriously injured. We had to keep asking them to get out of the way, but sometimes they completely ignore you.
Thanks Micheal!
