It's to my understanding that they will be recovering the original look of green complex and bunkers on #16. That would be a great thing.
I would like to see them recover the length and strategies on #2. I think it would work much better as a three-shot hole from the original tee.
Also, it will never be able to be recovered, but the elimination of the tree line between holes 6 & 7 and 10 & 17 creating and opening up the strategies that those holes once possessed and has been lost. Yes, it would be dangerous and impractical. Yes, I'm being delusional.....
The entire front bunker area of #18 also needs to be redone or rebuilt. A lot of the original was washed away, but I've played one from down there before and it's a blast.
The entire Pasatiempo facility needs a much firmer and faster method of turf management.
Do all of the above, and the sky's the limit. A wonderful place.
