It's a little disappointing (but not unexpected) that only a couple of people have responded to this post. But I am 100% behind getting a local group together. I am acquainted with handful of local owners and I think mmeyer86GT may know a bunch more. I'm sure that some of them are not active readers of this forum so lets all reach out and and make a personal contact with them and see what sort of interest we can drum up.
If you are a Pennock's reader in the greater Sacramento region chime in here, or at Dklosinski's new Facebook page noted above, to express your interest. And hey, maybe put out some feelers of your own.
Also, if I might suggest... An easy way to get started could be meeting up at one of the weekly Cars and Coffee events in Folsom, CA. A friend and I attended several months ago and found it to be well organized and well attended. They gather early every Saturday morning so a few of us might agree to choose a particular Saturday just to get the ball rolling.
From their web site... "Come visit, bring your classic car, truck or motorcycles every Saturday 7am-9am at 430 Palladio Parkway, Folsom, Ca 95630
Near Sports Authority" http://carsandcoffeefolsom.com/
