On several occasions I've written that Colwood is likely the first course built west of the Mississippi to compare (at least somewhat) favourably with the best courses in the east. I can't think of any other course in the west built during the pre-WWI era that compares with Colwood.
And, although there have been changes at Colwood over the years (some directed by Macan, himself), the basic structure of the course and most of the greens date to its original construction, as I understand. Dale?
