I am building a track where you drive through a town and then you have to do a hillclimb into a tunnel and back to the town. I am using many materials for the surface. It is not done but I wanted to see what you thought. I might post pics soon.
I would love to see pictures! I am also begining on a track (for DigiQs). I f you have found a good surface to make the track from please let me know. Post some pics soon!
