I'm definitely going to attend the Monterey Historics on Saturday. Is it also worth going on Friday or Sunday? Friday is the Concorso Italiano. Sunday is the Pebble Beach Concours. And I want to leave time for cruising the California country-side. Soooo, what's happening on Friday or Sunday that doesn't happen on Saturday??? Also, is there only open grandstand seating at the Historics? Or is there something better? Thanks!
