I have found Cottonmouths right on PGA Blvd. If you drive out passed PGA there are train tracks over that way. There is pond next to the train tracks. (sorry I don't remember the name of the Rode). I would also suggest going to Stewart to Jonathan Dickinson State Park. You should see some cool stuff there. I am not sure if you plan on collecting but I would not suggest collecting in the park. When I go there I try to stay out of site. I feel kind of funny flipping stuff with people watching me. There are ranger around keeping an eye on things. I don't think I would bring a snake stick to the park.
