Saw this snake around 5:30pm hanging out on the side of the trail. It then crossed the trail to get to the other side back into the bushes.

The next snake I found was a ruber coiled up under part of block wall but it went deep under before I could get any pics. Right on the other side of wall I flipped a piece of metal and found this big Oreganus.

I was hoping with the warm up that snakes might be moving but the only one we saw was this DOR juvenile rattler. We also saw a tree frog and toad but did not stop for pics.
