Why the title? Simply because when I was 60, I wanted to spend a few weeks travelling route 66, which, for various reasons did not materialise, then recently I watched a TV cookery programme where the presenters/cooks were travelling route 66 as I was typing some notes for this book - and I thought about adding an additional 6 to the famous route. Hopefully no one will think this is a travel book wondering where route 666 is, as it is not a route...
