I don't play Golf. So 20? (random guess there!).
And I don't play golf at Barlaston Golf Club (one end of my road) or Trentham Golf Club (the other end believe it or not!).
I drive past one or the other daily and wonder what it'd be like if I enjoyed it but I don't think I could be bothered to whack a ball and then go get it.
My dad and loads of his mates used to play it (they all still do, he just doesn't) and I've had offers to go but other than the pee-up part I think I'd get bored. Unless it was jackass style with big horns and jumping sand pits in golf carts.
