i was going to check out green's... seeing its only about a hour or so from me.. As far as heads up goes. There has been attempts to do heads up in the past.. nobody can agree on a class structure that everyone thinks is fair.. and entries are low. IMO 0-421 and 421-500 seems fair.. but.. then you'll have the Stock cylinder guys complaining. Some of us old timers have seen the classes come and go.
I try and make fatherday weekend at silver lake.. its my birthday and there no other place I'd rather be.
