I think I have a Northwestern garter. I have live and dead minnows, and I don't know the last time he/she ate because I caught it on Saturday afternoon. There were at least twenty snakes in the area where I caught it.
I've got a couple pictures, but I need to figure out how to post them. It is mostly brown, with a yellow stripe going straight down it's back and one on each side. In between the yellow, it has sort of a checkered pattern trading off between red and brown. Underneath its belly its sort of a milky blue with speckles of orange every now and then and some dark blue. Its tounge is red, but the fork is a dark blue color (almost black). She shed on Sunday night. The picture that is my Avatar is him/her, I don't know if you can see it, but that is her.
