What's your favorite circuit? ...and why?

My number 1 would have to be Melbourne... Short and sweet, doesn't let you cut corners, narrow but still has opportunities to pass.

Number 2...  Mount Panorama... Pros:  simply a beautiful place to race, has good technical sections, the straights satisfy the need for speed.  Cons:  it's a long circuit, so with a 4+ lapper, it's difficult to get through it without getting interrupted; the straights (I know, this was a "pro" as well, but it's what makes the circuit so long, and with a marginal car, it's hard to keep up (or catch up) with the leader.
