Photo: Identify this snake! (Update: Valley Gartersnake!)

Anyone know this snake species? I bet my friend Durso does! We found it on the road nearby. It didn’t have any external wounds but was very limp. Hmm… #identifythis

Update: Thanks to Andrew Durso for identifying this snake as a Valley Gartersnake (Thamnophis sirtalis fitchi)!
