My father and I are going up to alaska this year for silver salmon. We will be at a place called cordova for the 2 weeks that we are in alaska(in august). Even though I have read for hours on the subject of flyfishing for silvers, I don't know exactly what i should bring for flies. I think I Will have 3 fly boxes.

Box one-

Box two-
Surface flies like wogs and mice

Box three-
Sub surface flies like pink bunny leaches

If you could help me out with this that would be great,
