Keith,
Could you elaborate?
Mike,
I'm not Keith, but yes, two of the three courses there (the Blue and the White) both utilize the double green.
Eisenhower park has three courses; Red, White, and Blue. When my mom was growing up there between 1946-1972, it was known as Salisbury park. The PGA was held on the Red course in the 1920s.
Blue and White are public-course Trent Jones. Conditioning is as expected, as play is heavy on all courses; since the Senior tour plays/played on Red, that course is "protected" from excessive play a little more than the other two. They utilize separate tee boxes for each green, but they are relatively identical (same length, same basic bunker sizes/shapes).
Eisenhower is geographically between GCGC and Bethpage, but closer in distance to GC.
