Continuing toward the opening Spring Hill Campground, I am installing board and bat siding today. We will show how it is traditionally done and how this is a little non-traditional. It is technically Board and Batten siding. Most people abbreviate the name to board and bat. The Definition of a batten is along, flat strip of squared wood or metal used to hold something in place or as a fastening against a wall. This installation allows for expansion and contraction of the wood. @FlanaganHomestead
