With my ShoWagon and my Valentine 1, I was generally running faster than just about everybody else, and when I would come up behind someone in the left lane passing a string of trucks, he would usually dart in between the trucks to let me by, then come back out and continue his pass.

You've mentioned this before, and I wonder about something...

This is just a theory I'm postulating, mind you...

Perhaps the reason you've noticed people yielding the left lane isn't because they're any more courteous than other parts of the country...

Maybe it's because the unmarked state police in their area tend to drive gray Tauruses, and they think you're the fuzz because you're coming up on them so fast from behind.
