You know you've been driving too many hours if..

You stop at Sun Mart because the espresso stand is closed and you tell the clerk the coffee tastes as good as Starbucks and is a lot cheaper......

For miles you follow a sports care going 80 with "I see slow people" and a radioactive sign painted on the back of it...and then pass him 'cause he's going too slow. (Needless to say, it is no big surprise when he gets off in Richland.)....

You start calling the driver in front of you "the Bozo in the Benz" because the outline of his balding head looks like a silhouette of the famous clown...

You actually see the shocked expression on the driver next to you as his left rear window explodes into glass fragments. No telling what hit it....

You pass numerous cop cars and don't even bother to slow down...

On the one hand, you start calling every slow driver in the left lane "a little old lady", but on the other hand, you fear that some day you will be among that number....
