Last year I found,
Timber rattelsnakes
Northern copperheads
Eastern gartersnakes
Black ratsnakes
Black racers
Northern watersnakes
Northern ringnecks

.....hmm think that's about it...also did an outwest trip where I found a Gopher snake. This next year I've got trips planned or in the planning for the panhandle of Florida - Outerbanks, NC - Manitoba, Canada - and tons of day or weekend trips to spots around PA, MD, DE, VA, and NJ.
