Hillcrest is definitely walkable, can’t say much about the size of their “player” group. Crane Creek is in the foothills and more of a hike. it was recently renovated by David Druzisky and, I think, considerably improved. SpurWing, in my opinion, is a quite bland design but probably more walkable than Crane Creek.
If you are interested, I could give you a good player contact name at each of these 3 private courses. When I say good player I am talking low single digit handicap.
