A Link
The A70 West of Edinburgh, just at Harperrig Reservoir. About 5 miles of dead straight, reasonably surfaced, good visibility drag strip followed by this set-square set of corners, then immediately after by an absolutely manic no-visibility corkscrew left-right up-down beast of a bend.
The one-way road around the back side of Holyrood Park in Edinburgh, fantastic... Up and downy, potentially incredibly fast if you do it at dawn or dusk (too many people around at other times, just wouldn't be safe or responsible)
