Racing Leagues in the USA - Open Wheel or Sports Cars

[imsa.gtp1]

Having put rF1 aside in 2011 I've recently returned to rF2.

Is anyone in the USA doing any league racing for open wheel or prototype Sports cars?

Group C, F1, or Indycars in particular.

I used to run a league for F1 on rF1 but don't have the ambition anymore.

But I wouldn't mind joining a league for a few races running with other gentleman racers.

IMSA GTP
