Hi mate
Sorry, don't know of any specificly biker centric pubs around there. Millions of nice country pubs on the backroads though - I ride around that part of the world from time-to-time - and I've never failed to receive a warm welcome and a tea on request.
I know what you mean about the oakdene gravel pit - should try pulling out of there on my 1400, it just spins up and throws rocks at everyone
