I heard that Fast is filling up quickly for next summer - like booking into August already. Those of you considering doing the school might want to book soon, after this weekends bike show there will probably be slim pickins left for dates to choose. I personally think FAST is the way to go if you've never been on the track before -- they teach you all the correct technical skills and bring you up to a decent pace gradually over the course of the day. Even if you have years of street riding experience it is a completely different world at speed on a track so the instruction is a good thing ( it also helps your skills back on the street). For those who have been on the track before there are lots of groups that offer track days cheaper than Fast if you have a bike to use or rent.
Just my .02.
