This morning while hooking up the car for towing I noticed a penny on the ground. I placed it on the back bumper of the motorhome and continued the hookup process, then promptly forgot it until we were moving down the road. Some 160 miles of 2-lane, up to 11% grade and it made the trip for the entire day. Guess the road was not as rough as I thought.
That 11% grade for 4 kilometers is by the way the 1st time I have noted 4 “runaway truck ramps” on one hill.
