In the case of Bandon, we have the presence of the sea, albeit from clifftops rather than the traditional low-lying linksland. However, as Doak says: "...alluvial deposits from the Coquille River are blown back ashore to create a sandy paradise for American golfers."
It's fine to split hairs, but the nature of the turf and the shots you can play around the greens at Pacific Dunes make it worthy of inclusion in my book. With certain factors (f&f, wind, a rugged natural setting) in place, "links" becomes a state of mind in my opinion....I definitely think the Bandon courses have an intensity of links feeling that I haven't always had at a few technically "true links".
