Bob,
I'm very happy to hear you got a chance to return to Riviera. Hopefully you didn't play on a Monday and have to play the alternate greens on # 6, 10 & 16!
I suspect they were not in place back in 1975. I am some what puzzled by your observation that the condition of the course has greatly improved? Although I have only had the opportunity to play there once, back in 1985, I did attend many LA Opens in the 80's and never detected anything but the finest conditions for golf. I would agree that eucalyptus trees, especially the very large blue gums, did tend to dominate the landscape at that time. I doubt that their planters ever intened them to get quite that big. I suspect that although the course might loose some saftey factor if they were removed completely, the strategy that Thomas intended would remain intact. The heady scent of eucalyptus in flower, to this day, reminds me of Riviera!
