Bill,
I came across this whilst browsing the other day on another forum :-
Chin and Safe. Safe is like you described; it's a goddamn free-for-all but still stays pretty safe somehow.
Chin is pretty well structured with classroom sessions. They mark the Novice cars with the "X" and the head instructor has to solo you out before you can drive alone. They even keep a file with notes about you as you work up to be released as solo.
Sample schedule (Note classroom sessions) Chin Motorsports
Cheers,
Russ
