I've done this road countless times.. love it! over Rannoch moor and through Glen Coe (we did it on the Scottish road trip this year) if it really was the Scottish government who commissioned this advert hats off to them and another one from them the Kinlochleven loop..we did that too! check out the website http://dontriskit.info/breathtaking-roads/
Horizontal rain on Rannoch Moor. Sunshine and wet patches on the Kinlochleven loop. Ah those memories. Deep, deep joy. SIGH!!
