I want to build a track. My first attempt was pretty laim. I went to Home depot and bought two 2'x4' 1/4 inch hard boards and some rope. I soon figured out that the rope is not high enough and the car can go over it.
Does anybody have any recommendations on side rails that are tall enough and let the car skid on if it hits a wall?
Also what is a typical track size? I am thinking that 4'x4' is not going to be big enough. It would be nice to keep the track modular because I live in an apartment and don't have much space.
