My area, yes repeat these!
1st choice: Sears Point(less) and workers that join in the fun, plus a track where driving skill means more than having a V-8 Volvo (which has both skill and a V-8)
2nd choice: Buttonwillow in the heat, the cold, the middle of nowhere... don't much need to say more - but if you can find the track and get there, and you needed spares, enjoy the beer ;-)
3rd, but actually close to 1st: Thunderhill, more than in the middle of nowhere, but with a Wally-world down the street for all the oil and cleaning supplies you (will definitely) need -- BUT, I want a chicane in one or both of the straights to even up the 120mph cars with the 80mph ones - it's like reading a phone book with someone pointing a gun at your head when you have a 'real' crap-can of a car at the end of those... and even *more* fun if you don't really need to lift for the following corners :+P
On the "I'd never" list: Willow Springs 2.5m original This course has only 2-1/2 turns if you have less than a gazzilion hp and the off-course excursion is into grapefruit sized kitty-litter.
~that said, The Streets of Willow is a cool, tight and a bit frustrating course...(in traffic) ...with off course obstacles of peach-sized kitty-litter.
~dunno 'bout the newest incarnation of Willow, as I have no desire to go back there until I can afford a gazzilion hp.
Also "Never" but for entirely different reasons: Laguna Seca - they have curfews. Major Curfews - I'm surprised they don't make cars running there have a radio-controlled cut-off so they can shut down at precisely 5pm. or is it 4:30?
the ones that got away:
-- for those in the other half of CA, If I could guarantee my tow-vehicle, income and time would allow, I'd love to do Coronado, Pomona, Country Club, and even Las Vegas...
