If you have Google Earth, check out the aerials from 2004, which was when I first played it. This was the last year of what I assume was the original routing.
In 2005, they decided to add on to the development part of it and built a huge road through the middle of parts of the course, including the old 18th. 18 was a par 4 originally and isn't really near the new 18th par 3. It had a fairway landing area which ran out, requiring an aerial shot on the second. That land is all houses now. Wasn't a great hole, but better than the new 18th.
The road also removed the old 11th and 14th. The new 2nd is an atrocious hole. Although only 342 yards, it requires close to 200 yards carry to make the fairway (downhill) to a patch of fairway that then rises fairly significantly to the green.
I think any trace of the old 1st is gone too. It looks like they were trying to put houses on it, but as of the Google aerial, I don't see any on it. While I think the land is still there, the road would cut through the tee line for those cutting the dogleg. Liability city.
I'm not sure whose decision it was to add that development on Sugar Ridge, but it turned a Doak 1 into a Doak 0. I still think Pebble Creek takes the cake, because it very well may contain two of the worst par 5s in the world; and they're all on the same course.
