I began to freewheel at this corner by what was The Harvest Home PH. Nice pub BTW, but sadly only a B+B now.

I freewheeled all the way down through the Lumburn Bends, and then started turning the cranks here and found I'd lost all drive!

I found the chain here after walking more than 3miles home, fitting a spare chain, and going out looking. Why I didn't see it on the way home walking, I don't know, perhaps a car went by and hid it as I passed.
