I recall also an article *many* years ago in Buses Magazine of two
people doing a John O'Groats to Land's End trip in this way. Also, in
a later "Buses Annual" Stewart J. Brown and Gavin Booth did a cross
country trip from I think Liverpool to Hull in this way.

It's one of those things I've toyed with trying many times but alas it's
harder these days as the bus network has some remarkable gaps sometimes.
A Birmingham - Bristol trip in this way was a long-held ambition of mine
but there appears now to be no realistic way of going by bus from
Gloucester to Bristol, amazingly.

In the good old days of the National Wanderbus Pass (£2.97: Hants &
Dorset issued it as 3 x 99p tickets) I made several longish journeys
from Bulford, e.g.

Bulford - Salisbury - Southampton - Portsmouth - Brighton - Seaford
Bulford - Andover - Basingstoke - Heathrow - London - Cambridge
Bulford - Andover - Newbury - Oxford - Coventry - Leicester
