What city was the last fight supposed to be in? I thought it was Las Vegas since they were coming from the Hoover Dam. But there were clearly a number of L.A. landmarks like Wilshire Blvd.

You're confusing a Michael Bay movie with one that has a solid sense of continuity. The guy knows how to create some awesomely intense, high energy scenes, but but god damn if he doesn't have a nasty habit of stockpiling factual errors and continuity goofs.

BTW, SilentAce -> Did you catch the APU goof with the AWACS?
