Used to have a toy as a kid which was fab. It was sort of a stiff cardboard "road" but all the bits slotted in together so you could make whatever road network you liked - complete with junctions and a roundabout. It also came with a little set of road signs. Was fab to run your toy cars around on it.
Would love to get something similar for the dses, but can't seem to find anything similar. Only those pre-printed car mats which are no where near as fun. Anyone know what that road jigsaw thing was called and if anything similar is still made?
