Aye, I reckon I'll be a regular visitor myself.
Its just over 70 miles for me, but it's mostly motorway and then 15 miles of the fantastic A702 - utterly deserted twisty fast A-road in great condition, it was a superb drive. I think on a good day without getting stuck in the morning rush hour, it would take about 1h10m - Its about 25 miles further away for me than Glentress, but there's not that much difference in time to drive.
