I am normally with anyone having a laugh at PC gone mad, etc, etc, but I can see the rationale for this decision I think. If you have limited resources, assess what targets you want to hit. Then figure out how to hit them. Let's face it, as a group, in general, white middle class people will have a a bit of an idea how to get it together to go for a walk by Coniston. People from Kurdish and Liberian origin living in poverty in Stoke-on-Trent won't. Which is why I have been involved in taking groups of such people to make music and walk in the Lake District. My white educated middle-class friends already know how to do this, so I dont need to help them.
    And for useful background information, listen to a copy of "A Trip to the Lakes" by the Boat Band. A truly excellent record, and competitively priced. Has nothing to do with the ethnic origins of fell-walkers, but has got many top-notch traditional Cumbrian tunes. The tenor banjo playing is particularly inspiring.
