Not going to argue, saucery she then proceeds to argue but that does rather depend on what one means by real mix!
I think Scotland is the only UK country with public golf courses. There were some in proper working class areas of Glasgow. Probably been built oevr now but there was one where I grew up.
Golf equipment, proper shoes, green fee and membership are all expensive. Playing the odd game maybe not so much.
It's like cricket these days which used to have proper working class representation but now, apart from in a few areas it is increasingly dominated by the public school attendees.
DH is a golf club member by the way so I have no axe to grind.
