Interestingly, the land on which Brentwood CC and Bel-Air CC (and Riviera to a slighly lesser degree)sit on is probably no less (and maybe more valuable) on an 18 hole psf or acre basis. I'd also add that Pebble Beach, CPC and maybe MPCC (Bob?) are also not that far off (if at all) in valuation.
In today's market, Sebonac, NGLA, Shinnecock & Southampton are also fairly valuable, however, the little known and much smaller Bridgehampton GC might equal the LACC per acre basis. Right now, an acre south of the hwy in that neighborhood goes for over $2M. Maidstone would also see at least those prices with seaside lots commanding close to $3-4M per.
I can't see anything in Chicago, Washington DC, Philly or Florida approaching this kind of obscene pricing.
