I agree with many of the comments on this thread and it is definitely nowhere near a best of list in my view, but at least it did make me go and play one of the courses listed, that being Leadhills.
The course is located a few miles off the M74 approx midway between Carlisle and Glasgow. It's an open moorland course with nice springy turf (after a dry summer that is) that apparently doubles as a ski slope during the winter. While I'm no agronomist I'd suggest the greens are 60% moss, 35% grass and 5% rabbit scrapings and must "run" at a good 2 or 3 on the stimp. Needless to say the greenkeeping is basic.
Reputedly it's also the highest golf course in Scotland. It's not a long course even by nine holer standards but neither is it a pitch and putt. There are a couple of really quite good holes where you drive over a gully. For the paint by numbers crowd, the stats for it are 2,296 yards from the tips with a slope rating of 105.
By no means a bad course, and good fun to play provided you enter into the spirit of things, however wouldn't crack my own personal top ten in Scotland never mind the UK.
