Lately I've been working on hiding some of the substructure features of circuit. I race quite a bit with only a few guys and can actually marshall the track almost entirely from the drivers stations. So I began fabricating removeable or moveable scenic items beginning with the Circle Lot. This is a couple of 1/4 inch pieces of foam glued together and reinforced underneath with dowel rods. I scored the foam for concrete breaks and did a little rock and grass scaping to hide the edges when the cover is in place. Many people are quite surprised when I take out the Circle Lot for a big night of racing. The best of both worlds, good track access and complete scenic!
