I'm just wondering if Tom means the "Buchan Way" as opposed to "Buchanan Way"?

There's the
John Buchan Way from Peebles to Broughton (13-14 miles), not to be confused with the longer
Formatine and Buchan Way which is in Aberdeenshire.
Also, replying to bsmyth, I found only two operators offering Borders Abbey Way: apart from
Contours (whom you used) there is also
SCsupport. Does anybody know any others?
