Well, I don't know how to PM and since you are leaving tomorrow I don't have time to figure it out... so I will give you his name...
Mark Tarabochia. They will know who he is... my family has been fishing out of that cannery for years.
Karluk would be a good trip.. if you have a rifle. Go to the head of Larsen Bay and there is an easy trail for about 45 minutes. I got chase by a bear there in '78. What an adrenaline rush. My friend carrying the fish should have dropped them. We had two rifles and damn glad we did. Bring a bug net for your head.
