I don't remember that car that Randy Hampton raced back then but I was probably too focused on how Richard Petty was doing at the time. To me, the period through the mid-sixties to early-seventies was the best era for NASCAR. Being able to reproduce it has been a lot of fun.
I was tempted to build a4 to 8 lane oval instead of my current layout but after watching YouTube videos of people using those tracks, - they seemed sort of boring. NASCAR did run road courses so this isn't totally inappropriate.
It's time to dust off those old tracks you've held onto.
