Flowers Sheds and Snakes...Oh My

We have been busy the past few days. We now have lots of flowers planted in the front flowerbed. Hubs is putting the finishing touches on the shed as I type. And we have discovered that being this close to the lake means the snakes like to visit our yard. So far I haven't actually seen them, only Hubs. I'm not sure if it's just the harmless garden snake or not. I know that they had problems last summer with water moccasins so I hope it's not them slithering in my yard. Should be interesting if the dog finds one, she plays with anything that moves and would just love to have a snake I'm sure. As for me, I would just as soon figure out a way to keep them out of the backyard.
