That'll be St. Mary's Loch. Not far from my house. It does get more than it's fair share of power rangers at the weekend and often a bit of police presence, but during the week it's empty apart from the odd tractor! Did you buy a tartan tin of shortbread at Moffat? or perhaps a tin of Moffat Toffee? Did you even head to Moffat? Good alternative is to head for Tweedsmuir via Meggat dam and back round by Peebles. There aint much to see on the Moffat road beyond the Grey Mares Tail and even less to see in Moffat itself apart from 100,000 pensioners buying woolly jumpers.
