My favorite is the Monaco Circuit, the surroundings are beautiful, you always see boats and luxury cars, and the track is just great!!

To watch.. monaco.
To drive.. so far road atlanta.

norbering would prolly replace both if I were alive when they were doing the whole thing.

I've never been to a racetrack (nothing even close to Vancouver), but I'd have to say Spa because of the scenery, the high speed corners, the elevation changes, and the challenge that it gives the driver. I think Spa has some of the most challenging corners in the world. Case in ponit: Eau Rouge.

Montreal, I actually learned to drive on it... much better than a parking lot 8)
