Not sure if you guys know about this. I go every year. They sell cool memorabilia - hats, shirts, books, die cast, whatever.
Plus, you also have all the Conti dealer stuff (Ferrari, Mas), but the big thing is they clear out the service bays and bring in awesome cars - including Weinbergers rare Ferraris - think 50's 166MM worth around $5M.
Great thing to do an a cold Saturday morning. I'll be there:
