Alaska in June

I'll be in the Anchorage area the last week in June and would like to know
whether I should concentrate my efforts in the Susitna river area, the Kenai
Peninsula area, or the Copper valley. I am not interested in King salmon, I
would like to fish for Red salmon, rainbow trout, or Dollies in some area where
there aren't too many people ( 5wt to 9wt stuff). Any info or recommendations I
could get would be greatly appreciated. Thanks.
