I never play the par three courses either (WGT or in real golf).
There are some good courses at Brandon Dunes but the WGT model is just the US Open courses and I don't think these will ever get picked to host an Open. PGA yes but they just don't fit into the Open mode, especially after the last two courses Chambers Bay and Erin Hills which were a failure in terms of hosting an Open.
If I remember correctly, the US is going back to traditional courses for the next 10 years or so, Shinnecock Hills, Winged Foot, Pinehurst, Pebble Beach, etc. which means we will get some nice courses, I just wish they would add an agreement with the PGA as well so we can get some of those courses.
