That was probably part of the Annual Pebble Beach Concours d’Elegance. It runs most of, if not all of the week before. Vintage car races at Laguna Seca, auctions, ridiculous cars at Pebble Beach Golf course, and the finale is the concours competion on Sunday. After seeing the cars on the road, my wife suggested I make plans to go next year. I didn't need for her to ask twice. Called my cousin in the midwest on the spot and told him to make plans to come out next August and take a road trip with me.
