If there isn't a bus, I don't hang around, I just hitchhike. Worked a treat for me a couple of weeks ago. I got to within 8 miles of my starting point by train and bus, nothing else available other than to be 'polite' and walk, or to hitch. I hitched, 3 cars later (2 minutes waiting time) and a young woman receptionist from the local GP service stopped and took me straight to my chosen camp site.
