There was the time I was driving from near Ross on the SE Welsh border to the NW of Wales, via the Heads of the Valleys and the A470 about ten years ago.
Could I see any petrol stations? Could I heck! I was watching the gauge go down and the estimated range drop below 30 miles. It was getting late and the villages were getting further and further apart. It was more than 60 miles to the next petrol station I was certain would be open 24 hours, in Porthmadog.
And then I came to the village of Caersws at 9.50pm. The petrol station was scheduled to close at 10pm. A sigh of relief!
