The marketing copy on the home page is awesome. It's going straight into my files.
"In 1774, Dutch settlers made New Hempstead their home and history was made. Even then, a place called New Amsterdam, now known as New York City, was not too far to travel to. History was written again in 1996 as New York Country Club opened its gates in these historic hills. Now in its 10th year, New York Country Club has become a hidden jewel in the tree-lined hills of Rockland County, a place that many golfers have tried to keep secret for many years."
After all, not much happened in New York between 1774 and 1996. And if you want to write some history, you definitely want to choose some historic hills that are not in New Amsterdam (now known as New York, FYI) and also avoid newly-formed hills where nothing has ever happened.
When you've succeeded in this mission, the next thing you do is build a website to point out that the club is a secret, and has been so for many years (i.e., ten years, or, if you prefer, ten years two years ago).
