I figured you might have an issue with the thinner glass.

Dad's original idea was canvas like we used to have years ago. Brainstorming ended up with the plexiglass idea. Of course, everytime I would run up or down the river in the spring, he would always talk about how nice it would be to have one. Then he makes one for himself!!!

Funny thing, I just throw one of my fishing bags in the space and it blocks the hole off perfectly. People would be amazed at how much air comes through there.
