We were dirt, but as he and anyone that raced can tell you, by the time the feature came around, that dirt was hot and hard packed with a surface close to concrete :)
Anyway, these are just a couple examples of what I personally try to create in scale for the series and thought maybe a few of you might like it.

I'm working on the NOVA mold now. I am seriously thinking of moving the Snap-Tite Firebird back on the list and search for an older Scalextric Cougar to throw in the mix. Not to mention a 66-67 Revogram Charger.
