Tom, other than Merion, could you briefly explain each mystery? Also, I thought Bethpage Black used to be on this list.
Bethpage is another mystery, although IMO I think the evidence points to both men deserving some credit, with Tilly getting more than Burbeck.
I take it you understand the mysteries surrounding Merion.
Yale and Kittansett I've already mentioned.
Crystal Downs, I've not seen any evidence supporting the idea that Mackenzie designed the course.
At PVGC, was Crump involved in laying out the golf course, and what exactly should he be given credit for from design standpoint. Do Colt and Alison deserve more credit than they are presently given? Should Hugh Wilson and Tilly get some design credit?
Cypress Point, did Mackenzie use Raynor's routing?
Having OTM's name associated with golf course was, and still is, a great honor. Which of those courses does he deserve primary design credit as opposed to advisory credit, or even ceremonial credit?
