Dan,
I also attended the 70 Open, as a 15 year old. My biggest memory, aside from all the Dave Hill talk was following Trevino. At the time, he was endorsing cut proof Faultless brand golf balls, but the rumor was he didn't - gasp - actually play them. Well, on one hole, I was in the LZ, and he hit it in the rough near me (surprisingly I was on the left hand side) and I was leaning over, as the label was facing down in deep rough, trying to read it. Must have taken longer than I thought because I look up to hear Trevino, now right on top of me, say, "Back away son, my 7 iron in your forehead is the kind of souvenir you want from the US Open.....go buy a shirt or something."
As an aspiring golf course architect, I was struck by the number of sharp doglegs, even without the pros telling me it was bad every night on the local news. Also, a lot of small trees, which have now matured.
Back on topic, Wind's article about the same time was one of the first I read. Still have a Xerox copy of it, and just pulled it out a short while back. I usually read golf architecture books while watching hockey on TV....not like it needs 100% attention, especially if you have rewind.
