I like LB's inclusion of the Targa. One more fantasy circuit, a personal favorite of mine, the old Osterreichring. (most of which actually still exist, just tucked away behind fences, and over-grown with weeds.
Some of you would actually enjoy the DP's, individually they're loud & menacing, and a whole field of them makes a ridiculous noise, and the Corvette DP in particular is quite attractive.
