Snakes.. update

Well, it's not the end of July and we have seen no signs of anymore snakes. We've been on the playground a few times, with no trouble. We had a "snake specialist" guy from the zoo come out and he told us that all of our "snake holes" were not that. He informed us that snakes do not dig holes. They will sometimes use other animals holes, but they do not dig their own. He also told us that it is highly unlikely that poisonous snakes would live in our location. Hrm. So, we've relaxed a bit and are just assuming that the snakes have moved on.
