It’s apparently the UK’s most dreadful road. Here is how to avoid it, in the local tongue:
Just avoid the A9 eh?
Go North up the West coast, preferably avoiding Glesca by taking a Clyde ferry. Alternatively, take Mway to Perth and then North via Blairgowrie, Glenshee, Braemar, the Lecht , Grantown, Nairn and Inversneckie (Inverness).
All us natives ken that fine!.....
