If you were going anywhere on the thumb in the 60's. Going north you called in at The Last Chance, and if you were going south west it was Smoky Joe's. As you say before the advent of the motorway you never knew who you would bump in to having a bacon sandwich.
I haven't got a photo of Smoky Joe's, but I managed to find this one of The Last Chance (a not very good one).
Something else this modern world has put an end to, hitch hiking. Who would stop now to give someone a lift who was o the thumb. You would have to be a brave or foolish person.
