DAVID R ROSS is at his happiest stravaiging Scotland on his motorcycle, rummelling around ruins and battle sites, and standing on the spots where the great and not so great of Scots history once stood. Real happiness is when you are so engrossed in whatever you are doing that time has no meaning, and you forget to eat, till the rumbling in your stomach reminds you that it has been many hours since you last saw food. He is the author of several highly successful books of Scottish history; On the Trail of William Wallace, On the Trail of Robert the Bruce, On the Trail of Bonnie Prince Charlie, A Passion for Scotland and Desire Lines.
