The day was sweltering as we left Cambridge. After initial delays in traffic, the convoy made good progress north; it grew cooler, and as the cars passed Newcastle, tendrils of fog swept in and thickened until we found ourselves driving through a cloud.
It reached its thickest about sixty miles short of Edinburgh. Unable to see more than a few dozen metres ahead, I half-expected to see bolts of lightning as we passed the "Scotland welcomes you" sign. The fog lifted, however, and it grew warm again as we entered the city.
