This blonde cowgirl is hauling to a show in Northern Idaho in late november and she is behind another rig.. the rig stops at RR, and the cowgirl gets out and runs up to the other rig and says "mister your loosing some of your load" the driver rolls his eyes and proceeds down the road.
At the next stop she does the same thing, He shakes his head and moves along. She does it again, and again... this time He takes off faster comes to the next stop and He jumps out. Runs back to the Cowgirl and knock on Her window and says...

Lady I know I am loosing my Load, I am salting the Road...!..
