Why do I ask you ask? Well then you didn't read my gaming post below. The answer: about 400 square miles, 20 miles/side. To give people an idea of just how BIG an area that is to fuck around in, here are some equivalent areas in the real world (they are slightly bigger, but close): That means it is possible, if you are on foot and had no vehicles, to have 8 hours of walking, or 3-4 hours of running. Driving: 20 minutes, assuming you obey the speed limit and are on a highway (unlikely). Still 10 minutes of driving if you can maintain a 120 miles/hr average... all to get from one point in the game to another.
