By this time we discovered that our gadgets were useless.
(Yes, that's a police cruiser at the far end. He followed us into the rest area, and then left wordlessly.) There was no cell phone coverage for anyone, digital, analog- nada, zip, dead, NO SERVICE.
Talkabouts were useless between the rolling hills. The trees were changing colors in turn, some still fresh green and others almost on fire with color.
So we would pull over and wave and rely on the quick reflexes and wonderful BMW brakes of our fellow Z3'ers.
Then they back up to where we were waiting.
We took the last leg to lunch in formation.
We saw Elvis again at lunch, many bits of memorabilia including a poster for one of Elvis's performances where tickets had cost $1.75.
