Concur re Walton Heath - and Brent, make sure you spend some time in the cluhbouse... they have a GREAT bar, but more importantly some of the coolest pics you'll ever see, from the 1981 Ryder Cup held there.
But you can't respond to that, as it's not about architecture. So just politely nod.
Question re London environs: I have no clue if this is north, south, east, west... but when I was there several years ago, I played a course called North Hants GC. I remember it being pretty darn fun.. sorta heathery (but not close to Walton Heath), some rocky parts, great greens, very welcoming club. Any comments on North Hants?
