I see them very often on the farm in pennsylvania. I advise against getting a WC smooth green. For one, its probably illegal everywhere, as thy are not exactly in good standings, because if idiots like that farmer. Second, as a kid when I knew no better I kept some as pets. They would live happily in their viv and feast on insects for me, but always die within a few months. Wild caught's simply don't do well in captivity. Try going for a captive bred rought green snake. It's not illgal to own and even better, it's CB. I see specimens pop up from time to time.
