I got the idea to make paper boats with the kids and then float them on the C&O canal. The kids thought that was brilliant, although we might have picked a bad spot to launch our boats because there was not a great view to watch them sail away and there was a fish dying in the water right in front of us.
Violette's boat capsized almost immediately from getting dunked in the water when she tried to push it with a stick, but she didn't want to put her's in the water and was quite sad to have lost her boat.
The older two were happy though, and raced down the path to get a glimpse of their boats. One got caught in the bushes and we just barely made it back to the van before it rained.
