Wow, I didn't read or see the original thread from a few weeks ago. It was a nice afternoon read and I'm glad that Tom Dunne posted the links. Most hearty good wishes to Mr Edel and Metropolitan RED group on this project and their great archie-build team of Mike, Joe and crew.
Combining some questions I would have asked on the original had I seen it, and asking them here:
Can anyone indentify and post the name and location of any other 9 double green loop golf courses, that yield a round of 18 holes?
Is anyone aware of other experimentations with this sort of configuration historically, and can you cite them?
How much different is this than the few Japanese courses that have double greens? Aren't they more for the purpose of having 'winter greens' and are not played in multiple loops from different tees to double up on the possible holes available to be played?
The only course I know of that is truly a double loop of 9 holes with dual greens (some separate greens divided by 20-50 yards and some one dual green dual pin location design) is right here near me, called Thornberry Creek. It has been a public course, that opened as the dual 9 hole, then with grandiose plans, morphed into a new 18 holes built in addition to the sporty 9 hole dual loop, with a parade of homes subdivision R.E. plan, McMansion district. They added a huge austintatious clubhouse and then bled to death, culminating in a foreclosure/bankruptcy last year.
Did Mike, or Joe or anyone involved in El Boqueron visit Thornberry Creek as a point of research? They had some unforseen early problems with pacing and scheduling tee times and spacing of players that wanted to go around once or twice.
Ironically today, that course has reopened under the new ownership of the Oneida Tribe of Indians.
The original dual nine hole loop (as well as the added 18 hole championship parade of homes project) was designed by Rick Jacobsen. I wonder if anyone ever inquired of Jacobsen if he knew of the MacKenzie El Boqueron project, and if he modeled his work ideas on that.
Here is aerial-birds eye showing greens at 1rst (dual)-5th two seperate greens -6th (dual), you can move the image around to see whole routing.
