I HIGHLY recommend Tony's Track Days. Really well run outfit that attracts responsible, safety-conscious riders. Very different from the Wild West crew that some other organizations cater to.
If you're the guy who just wants to brrraaaapppp and SEND IT, yo, maybe TTD is not for you. If you want to actually learn to be a better rider, it definitely is.
Palmer is flat-out awesome....
