This is my board. 130x80 inches. At an inch to fifty yards I can do some reasonably big games for CD, but it is not the largest board I've had. When living on the east coast I had a board that was 200x100, which was actually a bit too big when try to manage units around the center. We solved this by having some handy little steps on either side of the table, which could be moved easily. Am trying to find the time to do a couple of mock-ups for Inchon, so as to get the ground scale accurate, and will post a couple of pictures later.
