From Jonah Goldberg at The Corner I found this little game. (This is the harder version of the US geography game.) It's easy to place the states along the coasts and the southern border, but the interior states and the Mountain West can be hard to pin down. See if you can beat my score:
Score: 80%
Average Error: 17 miles
Time: 376 seconds
The average error is the true test of how close you are.
