It looks like our snake decided to invite some friends over. We now check under the rock daily, to make sure the snake is still there, and here is what we found yesterday.
Today, the lighter-colored one has left, but the two darker ones are still there. Eric knew that Sarah had held one the other day, and it seemed fair to let him have his turn. I reminded him to be gentle, and he was. It was cooler today, and the snake was sluggish, which made it easier to hold, at least long enough for me to snap a picture.
