I just purchased a Overland limited set for my son and me for Christmas.  I would like to attach the track to a 4'x 8' sheet of 3/4.  My question is how can you attach the ez track directly to the plywood...or should i let the track sit freely.  I'm only adding a few details to start out so me and my son can build on it in the future.
