Me 1, dad 0. :]

Dad wanted me to spend the weekend screwing wood planks into spots on the wall where the plywood wasn't quite meshing together, so that no snow would get in through it this winter.

I took at look at said spots, and noticed that the spaces were less than a sixteenth of an inch wide. Got an idea: Get some nice, wide, sticky tape and slap it over the holes instead.

Dad's off to get said tape now. :]
