Flyphishr, I noticed your CIB. If you are retired military, the MWR facility on Elmendorf AFB can help. In late August, you may catch the 2nd silver run down South on the KenaI Penisula. You can also try Willow Creek not to far North if water levels permit. Go North up HW3 to where the HW crosses the creek. On the left, just past the bridge is the Willow Creek Resort. Call ahead, but you can rent a small inflatable pontoon there and do a self guided float trip. For a small fee, the folks at the resort will meet you downstream where the creek meets the Susitna River. Pack a lunch and It's a nice day on the water.
Also take the drive through Hatcher Pass Road while you are up there. You won't regret it.

Good Luck and enjoy the trip.
