Hi Matthew, and welcome to the forum. There are quite a few people on this forum that are really good at identifying garter, ribbon, and even water snakes, but they'll need to see a picture (and maybe ask you a few questions).
However, our site security protocol won't allow you to post pictures until you've made a few posts. This protocol cuts down on the amount of spam we receive. In the meantime, have a look around, and enjoy your stay.
Rick
P.S. Here's a link to a thread that will show how to post pictures (
Guide to posting pictures.).
