Maldives GP- beach racing!!
I was stationed on the island of Gan, whilst there I had a warning from our section commander about speeding; there was a straight piece of "road" on the way to one of the radar sites. We used to see how fast we could get up to in the Land Rover, the section commander was upstairs in the tower and saw the plume of dust; he then drove down to see who it was taking what he called "a considerably longer time" than I had. So if there is a Maldivian GP I claim the previous fastest lap.
