At a little park in Penetang, my son found a small stream and some wood to use as a shovel. He dug a little pond that was filled by the stream.
First, he thought that frogs could use it for their eggs. Then he decided that since it was deeper than the stream, people could wash their hands in it.
I admit I had just been filling time, waiting to get home and do stuff. The little Guy, on the other hand, was working to make Penetang a little better.
