Engineer Lake

There is this really neat lake (I've posted about before) on post. It's called "Engineer Lake".
Our Post has an Engineer unit here. I'm not sure if it's just a battallion or more. Anyway, there are lots of neat little musical things there. The boys love this one. When you step on the squares they make music. Jakob and Zack were trying their hardest to make them all work, and were not having much success.
