Pronghorn now allows reciprocal play on the Nicklaus course now that the Fazio course has opened.
My personal order of preference on the privates is: Pronghorn (Nicklaus), Crosswater, Broken Top Club, Awbrey Glen, Bend CC.
On the public side, my order of preference would be Sunriver (Woodlands), Aspen Lakes, Sunriver (Meadows), Eagle Crest (Ridge), Lost Tracks, Black Butte (Big Meadow), Eagle Crest (Resort), Quail Run, Widgi Creek, River's Edge, Black Butte (Glaze Meadow), Crooked River Ranch. I haven't played the new Juniper GC yet, but I'd assume it'd be in the better half of the public list.
