Liam and I found about 5-7 individuals, including a baby, which I couldn't take a picture of. Awesome snake, here's hoping they can make a comeback.

The Target Species-of-the-Day. It lived up to every moment of it's acclaimed " Most Beautiful Serpent in North America" status. Lots of slithering exit shots...and then...this. Thank you Tony, Zachary Lin and others that lead me to this...writhing prism.
