I bought a cheap plastic farm play set. It had tractors and trailers and fences and trees and other farm type items. I pulled the tractors and trailers apart and cut up the fences and trees. I used a flat piece as a base and glued the other bits on making sure the barricade was more or less the same width as the cardboard token supplied. Then it's just a matter of slapping on some paint and quick shade. The scale is not perfect but the effect is there and it works.
