Longest drive in UK, Aberdeen to London, and back the same night, left after work, (6pm) arrived back to start work (6am).
Longest drive (only comfort stops at the odd tree) in Aussie, was Kalgoorlie to Adelaide, straight thru, did it 3 times, in 2 years, not again.
Other longest, Townsville to Adelaide, only 4 hours sleep at Parke, in the car.
Back when young and silly.
Must be still in the blood though, as left midnight Christmas eve last, to go have Christmas dinner with my 90year old mum, and little sister, had dinner, washed the dishes, drove home.
Hamilton to Otaki, New Zealand. 6 hour trip each way.18 hour round trip.
cheers
