Here's my version of your WRC track.  After sitting for a year in a framed and routed state,
I just blasted away for about a day and did the prep, painting, taping and wiring.
It's quite fun with rally cars, Nascar's and my favorite the Scalextric IRL's.  Landscaping, a
timing system and the cross-over insert track piece to run a car in both lanes will follow.  
Others in our wood track group with limited space want a version, so more will be popping
