Just had the opportunity to play the newly "modified" Belvedere, unfortunately without pictures. I say "modified" rather than "restored" only because I suspect there will be many who barely notice the fantastic Willie Watson restoration work that took place this last Fall and Winter.
Most notably here, the bunker fronting the left of the long par 3 4th green was removed, and the original cross bunker ~120 yards from the tee was indeed rebuilt. Although it isn't in play for low handicappers, both my playing partner and I thought it served a useful visual purpose, as it creates the impression that the hole is shorter than it is.
In addition to some fantastic bunker removals and restorations (esp. left of 16 fairway), most of the greens were expanded to include some extremely interesting swales and humps that had been minimized by mowing practices over the years. Especially notable to me were 2, 6, 9, 11, 17, and 18. The greens weren't running very fast this week, and I wonder whether they'll be able to run them at their old speeds with the new expansions.
Since I know it's a favorite here, would love to hear others' thoughts on the restoration work.
