Given enough notice, I would definitely make either of those venues for a weekday event.
One thing I am concerned about - I keep hearing so much about the noise limit issues. I mean, how restrictive is it really? I'd hate to go all the way up there and then not be able to run. I can't believe my Miata is all that loud, but I've heard tales of otherwise street legal cars still being too loud for that track....nor cal racing club... they have two one day events at Laguna this year...
