Your a man of taste there Lorry, Can-Am was my first love.  Not going to boast BUT...I saw Mark Donohue and the Penske Porsche 917/30 race in person, never a more sublime combination of driver & car.  The first two racing cars I ever saw at speed were the factory McLaren M8F's of Denny Hulme and Peter Revson, doesn't get any better than that.
The race to the clouds is special too, for years the stomping ground of the Unser family, during the eighties the WRC teams brought some Group B rockets over to claim the hardware and greats like Walter Rohrl, Michele Mouton, Ari Vatanen, etc. graced the Rockies.
