The locations Pete is referring to is Paradise Hill Road, Brewster, WA 98812, just north of downtown Brewster.
I believe the satellite image is showing the first three Dye holes that they built after abandoning that project. DMC course is another 18 holes all together (by the same backers), but I am guessing it is built near that site.
It is only 30 min away from Chelan, which is a very popular vacation destination for local Seattleites so I don't think they will too much trouble getting people to visit. Other golf options at Chelan are not very good at all.
I do a 36 hole day to Wine Valley every year (4 hours each way). I wouldn't even hesitate making a trek out to this course if it is good.
