Back in 1977 when I was in my late 20s, I drove from Boston to Ohio, on day one, spent the night in a cheap motel, then drove from Ohio to Denver the second day (about 18 hours), spent the night in Denver, woke up to a broadcast on the radio that Elvis had died, then drove to California on the third day. It was exhausting!
Did KC to Denver in ‘81. Lost speed perception, hit a 35MPH offramp at 70. Never doing that again.
I did a run in a Northstar power STS from Decatur, Ga to the north side of Kansas City — 830 miles. I beat my normal time by about four hours — I’ll leave it at that.
