Imagine a street circuit with the main straight down the Las Vegas strip. I know I'm dreaming, but what a nice dream it is.

Coming back to the night races topic (and I apologize for starting another one without checking first).
If you want a city in the states to do it, I think NYC is the best. Imagine F1 cars driving around Manhattan. Of course, they'll have to repave some of the street, but imagine the exposure with the start finish line on Times Square.
And if you want extra fun, let the cabbies drive around as well, picking up and dropping off fans around the "track".
