Kenai river around the 20th of July. Fly to Anchorage, rent a car and book a cabin or tent camp in or near Soldotna would be the cheapest way to do it. Have your fish processed and shipped home right there in town.

Like Parker said, if they up the red limit to six... you'll be drownin' in sockeye fillets after 4 days. Easy, cheap and it'll definitely fill the freezer.

If you're lookin' for more of an experience than meat... I'd look somewhere else though.
