As far as the longevity of supers, there's probably some correlation between permancy of club administration or a certain "leave it alone" laissez faire atmosphere.
I'll give you three pretty good examples;
1. Merion, a club who had a basic "leave it alone" attitude for many decades---father, then son, supers, the Valentines. who lasted about 60 years.
2. Kittansett, a "leave it alone" great old seaside course in Mass, has had a super, Lennie Blodgett for close to 50 years.
3. PVGC, a basic "leave it alone" club whose czar, John Arthur Brown, and super Eb Steineger, came in together around 1925 and were there together for over 50 years!
