Just thinking, every course listed has been a US Open venue except for the courses across the pond (St. A, RSG) & Kiawah.
How long does WGT's deal with the USGA run for US Open courses?
If for a while we've got the likes of Shinnecock, Winged Foot, Torrey Pies, The Country Club, & LA Country club to look forward to in the next 5 years.
I'd imagine its a pretty large undertaking to do up a course for us to play on here -- might not be possible in 6 months or less. When we consider that, its understandable why courses are few and far between (i.e. yearly) b/c they've got to keep that deal with the USGA going.
Just another perspective...
