Hey nice pics of Nerodia sipedon sipedon, where were they taken at? I think in another post you had put you were in PA, as I am, that's why I ask. Me and Northerns have a rather dubious history.....they were the first snake I was ever bitten by (when I was 5yrs. old)....they can be so nasty at times, especially the little ones....LOL.
