Did my first ever YH dart last weekend. One of the best rides I've done for a while, if I can say so myself. A real spirit of adventure, reflecting a sense of travelling to a destination (something the best rides have in my opinion: Bryan Chapman, Denmead 400 etc).
I couldn't have picked better roads. Trace the obvious tracks on Dundee - Alyth - Pitlochry -Kinloch Rannoch via Foss - Aberfeldy - Bridge of Balgie - Crianlarich YH and you'll get the picture. Significant overlap with the Northern part of the Tayside Transgression, but with the lovely climb round Schiehallion and over the Lawers Road (the latter instead of the Glen Lyon dirt track).
I enjoyed it so much, I suspect I'll be doing more YH darts in the future. Street is around 200km from Redhill...
