Kyle -
Yeah, I have walked a few rounds on the older course. While it's got those brutally long par 4s (esp. the final trio), the thing that always got me was the shorter par 4s. The one on the front, #4 I think, just writes "double" on my scorecard every time. As for walkability, there's a couple streets to cross, but nothing too terrible.
Another good hole (for the pros) on the older course was #15, the long par 5 on the back. When playing into a N breeze (not prevailing in April, but occasional), it was just about at the limit of two shots. I think Daly hit an iron one time, and for Mickelson it was a baby 3W feathered in, but for most of them it was a full-blooded 3W to get home. Huge green too, meaning dumping it in a greenside bunker was no guarantee of an easy 4.
