Interesting to read your comments. I also had to change my plan on 2...strange the road was OOB further up but I didn't think it was sensible to run along either.
I rushed too much out of 4 (not helped by Dad being there at the same time) and took the longer route on one side of the map! Don't think it was very fair to have the best route off the side of map, thought I was being clever turning over early, but it was my own fault for not taking the time
Did exactly the same on number 6...was sure I'd seen a gap.
After dithering, I went a long way round to the north - i don't think Roger thought about turning the map back over, his route was south of mine, staying on side 2 of the map for as long as possible and hoping he could get through.
