Bill, '65 would have been difficult, even for Arnie, since he missed the cut with a pair of 76s. I was there, at Bellerive CC in St. Louis -- the only US Open I've attended. My next door neighbor, a golf lover, bought me a season's pass for $15 IIRC: I went to every day of practice, tournament and playoff, except Friday. Jack, btw, snuck in right on the cutline of 150 and never was a factor. Player won the playoff with Kel Nagle.
You're right about the others. As a big Arnie fan, I suffered watching his last round and playoff in 1966 on TV.
