All of those GMUs have produced game in the past for a lot of people. And there may be a lot of game out there still. I've never seen any, but I don't hunt up there. I've got other places.
Living in Vancouver, I know that the areas to the north, east and south of the correctional area are VERY popular for hunting, quads, outdoor rec and the such because of their close proximity to the Vancouver area.
568 is the Washougal area, if I remember off the top of my head, which includes the area around Stevenson. Good area. Always lots of sign.
572 is the Sioxon (sp?) around the Canyon Creek area. Like Kain said, its STEEP!! There's some logging around the 54 road that takes you to Carson, but otherwise its the deep, dark woods.
564 is Battle Ground. Wouldn't waste my time.
574 is the Wind River unit. That's a good area, but I haven't spent a lot of time around there because I've always had another place that I frequent a ton.
