Bill,
Respectfully, that view of 1 green at Philmont North also, upon thinking about it tonight, seems a little like our 8th hole green complex at Greate Bay. (Park, 1923-1927 timeframe). We met at Cricket last month--get in touch anytime and come down the AC Expressway if you haven't been here.
Philmont is on similar terrain as many Flynn-designed courses. Stands to reason there could be similarities. I just find it hard to believe that one receipt, journal entry, invoice, plan, note, etc, has not surfaced from any work done here, or even plans drawn but not carried out.
From my understanding of speaking to "those guys" that wrote the book, Flynn kept detailed, extensive records of work performed. As Steve has said repeatedly, 'oral history', for what that is worth, has been the only thing going. Why hasn't there been anything in writing surfacing? No news articles? (for whatever they're worth).
