Rain drops

It poured this morning. We could go out to the gym like I had planned because of the downpour. It was raining so hard I didn't think we could make it even out to the car without all of us getting soaked. So we stayed inside {the smart thing to do in such a downpour!} and did some fun things inside. 

See the river in our backyard? 

Can you guess what we did inside today?
