Quintessential should mean access by the public in general. While Pebble Beach does qualify, the price point is somewhat limiting. I'm going to nominate four courses that I feel meet the criteria and why:
1. Twisted Dune - kudos to Archie Struthers for building a place that began as a borrow pit and was flat as a pancake. Fairways are nice and wide for the average player, the forward tees allow the senior/women player to get around well; you can walk (I always do) and the price point to play is more than fair.
2. Wyncote - Chester County, PA - Fun public access layout that can be walked, great conditioning and price point is adjusted for day/time for tee times.
3. Paramus Golf Couse, Paramus, NJ - This really, truly municipal tract is sandwiched between Bergen Community College and Ridgewood Country Club. Flat, very well drained site that makes walking a breeze. This is a 3:15 round walking since green to tee separations are minimal.
4. Galloping Hill - Kenilworth, NJ - County owned course that was wonderfully re-done a few years ago. Again a good walk, though a bit hillier than the other 3 above.
