Today I drove the same route in the other direction. The Links Market (huge funfair), is making its annual visit to Kirkcaldy, which closes the main thoroughfare. This leads to hold ups on all the usual routes, and the Auchtertool road was the road that I new was clear. End to end, in similar conditions to my 108 mpg, I was only able to squeeze out 48.7 mpg. Shows how biased the road is in the one direction.
