Visionaries. Also an interesting question about what might have popularized great architecture in TX.
We had Hogan who did one course and quit because he didn't like the results with Joe Lee (and presumably the housing)
We had Byron Nelson, absolutely the nicest guy on earth, which may have hurt him architecturally. He partnered with a few different folks over the years - Plummer who he was very deferential to - and later Joe Finger, who was probably the dominant personality, and when older, briefly with DA Wiebring.
In Houston, you had Jackie Burke, who did build his version of Augusta National at Champions, but it was sort of the practical TX thing - big greens, housing to make money, etc. As pure as he wanted his club to be, he never had the NGLA type vision.
Marvin Leonard has his vision for Colonial but average land. Still stands among the best in state. Ditto later on with Preston Trail.
Like I said earlier, maybe the vision of the great local club lacked great local land. No self respecting Texan would build his dream course in Oregon, for Gawd sakes! (smiley inserted) Maybe Ruidoso, NM for a summer place, but that has little great stuff either.
Its just the way it happened, I guess.
