May 1998. Route 66 in Arizona, not far from the Grand Canyon.
So I had just bought a car after coming to the United States (a 1998 BMW 3-series coupe) and wanted to check out all of it's six cylinders. In a month, I put 6000 miles on it. Yes, all along the Pacific coast up to the Canadian border, and then to Grand Canyon and Death Valley. No mercy.
