Just to let everybody know, EFR is where the TM Master Cup Series, ARLA, and VSCC [formerly RROL] live. I've raced in all three [although I DNQ'd my only ARLA race]
TM Master Cup is the top level series, a combination of NASCAR and F1. The TM Lights is the developmental league. ARLA is like ARCA but it doesn't take itself to seriously. And that's what's great about ARLA. Drivers include "Ebenezer Quiggles Jr" and "Bigsby Foote" sponsored by Smash Beer, Sasq Watch Company, and Liguid Insomnia Energy. The CRL is a modified league. And the VSCC is a developmental series that's the place to start a career. It's primarily US based with a few races overseas.
