The story is that it dates back to "Central Region" days. A gritter slid off the road and they've not gritted it since - but there is a helluva lot more tourism up here since then - Sir Walter Scott running a lot more, a big Time-Share complex, several resturants, Lochs & Glens Hotel with their coach tours....
Both post ^^^^^ are right - they need to sort out the burst drains to stop water flowing across it and grit it BEFORE it freezes. Todays story is that they sent some specialist "ice buster" machine up there and it also failed....
I suggest their counterparts in Highland and Grampian would be laughing....
