This was the view of my friend in Leicester, whose dad, a bearded council head-of-this-or-that, is a regular orienteer.
"We're just a bunch of middle-class do-gooders"
This was a paraphrased quotation from the smoking discussion in 'Banter'.
"Vote Liberal Democrat"
That was the sign placed clearly in view of the crowd and finishers at one round of the World Cup / Surrey 5-O last year.
Unfair stereotyping? Let's see. With a view to this poll being potentially useful (to dispel myths / enable us to reach out to non-o sectors of the public), I've put it on the 'Discussion' forum. I'm sure the cartel will move it to Banter if necessary!

BTW I thought about having two categories: public sector / private sector; or working/middle/upper class, but I though they'd be a bit vague (with reference to contracting out in the first instance).
A point to debate: can anyone think of another sport with such a high level of 'public sector' participation? (I'm jumping the gun here, I know.)
