DAYT & BRO, it was no Pebble Beach but when the CCCA passed through Edmonton on a cross-continental tour about 20 years ago, I went out to meet them at their host hotel. By mingling and chatting folks up, I managed to talk my way into the back seat of a '39 Cadillac Sixty Special, for a drive to the then-new Reynolds Alberta Museum, about an hour out of town. The memory is still fresh and the people I met, enjoying all sorts of fabulous cars, were universally friendly and welcoming.
So I'd say hanging around the start of the Pebble Beach tour is also worth a shot, although security might be a whole lot tighter than it was for me in my sleepy little city. Wear your CCCA membership card on a lanyard 'round your neck - it might get you places.
