It just so happened that Grandpa Tom had a brand new basketball hoop that he wanted to set up while we were there. The basketball hoop just happened to come in a very large cardboard box. It just so happened that we had someone with us who really loves very large cardboard boxes and never lacks for creative ideas about how to use them. And it happens that Grandpa loves to power creative ideas. Thus:
Matthew's Cardboard Sailboat + Grandpa's Tractor Mower = Sailing at the Ponds
What a great memory!
