Chaz sounds like the parking break could have been dragging. check the amount of pad left on the rear. Jack up the rear and make sue the rear wheels turn freely when the brake is fully released.
Were you running the defroster at all to defog the windshield? The defroster will turn on the A/C pump to help dry the air. You would definately notice the drag.
On another note, Does anyone have a flatscreen tv wall mount they dont need?
