There was a small crowd and about a half dozen brand-new full size Dodges and two new Grand Cherokees on Hell's Gate when we pulled up. All had "Manufacturer" Michigan plates. I asked one of the guys if they were testing and he said ' Uh-yeah, just validating a couple of things" then walked off.
It was fun watching drivers who have absolutely no investment in their vehicle and full authorization to push it to it's limit even at the risk of severe damage.
They stopped for lunch after they had all done Hell's Gate and we thought we would drive ahead to the Escalator and eat lunch so we would be there when they caught up. We saw them come down Dragon's Tail, but they must have taken the cut-off back to the beginning of the trail because they never showed at Escalator.
