Garter snake "in the field"

[PanUzasny]

Finally caught this garter snake that I've seen a few times around my parents' house. I caught it in their garden - which I suppose could be a literal "field." It was fun to check out this big guy and then send him on his merry way. My kids like checking him out, but my sister - not so much.

I'm guessing it's a Thamnophis elegans, but if you have a better idea of what species it is, please let me know. Found in Utah, by the way.
