Tim,
Next time you're in Baltimore, I'd highly recommend Mount Pleasant, which used to host the "Eastern Open" in the 50s. Pine Ridge hosted the LPGA Championship for a number of years, as well.
Incidentally, both Mount Pleasant and Pine Ridge were designed by local parks superintendent Gus Hook. He also did city courses Carroll Park and Clifton Park, which are interesting as well, if shorter. He also made some additions and changes to Alex "Nipper" Campbell's Forest Park, another city course.
Some months back, Kye Goalby started a thread asking if anyone knew anything about Gus Hook after playing Mount Pleasant, as he was very impressed.
He has to be one of the most naturally gifted "amateur" architects in history, even given his limited, localized repetoire.
More amazingly, and germane to this discussion, is the fact that these courses get a tremendous amount of play, yet are maintained superbly with firm and fast conditions. Baltimore made me question ALL of my previous assumptions about "muni" golf.
