Our snake

Yesterday Rick and I saw a snake by the retaining wall in front of our house. It was a very small snake, probably just hatched this year, but I didn't recognize it (not that I have such a broad herpetological experience or anything). I took a photo (below) and looked it up online, and it seems to be a brown snake; Rick verified it with a better online reference. As we were looking at it, it crawled into the wall in a very small space between blocks. So now I guess we have a Resident Snake to help protect us from small insects.
