A number of my coworkers talk about GTA:SA a great deal, and one of the things that amuses me about their discussions is that, due to the size of the game world, they frequently run like this:

-Have you been over to City X yet?
-No, how do you get there?
-Well, you get on interstate Q and head north for ten minutes or so, then get on highway J and go east for about 25 minutes...
