I found this board a few days ago in a basement of a house in Georgia. I have a lake house and thought it would be fun for my daughter. But I've been trying to find some information about it because it has no markings on it whatsoever. From what i can tell, and i know nothing, but it looks like it was perhaps built from the Tom Blake Popular Mechanics article. There is no plug. Its 145 inches long and 22 inches wide. Anyone know anything about something like this?
