I'm sure all kinds of information is available, just shaking the right tree to get it:

Clams----I don't dig, any more but maybe publish the zip codes of where people live. I do know when the tides are good.....lot's of car, motor home, camper traffic....many stop at the Monty Square, East Aberdeen, Safeway...that I see. How much do they spend ?????

Salmon fishing...coast, should be able to get this ????? BUT THAT SAID, not like the middle 70's when 1000's of people came from all over the world to fish Westport. I remember 275+ charter boats, so many fish that boats couldn't clear the bar, done....back in for 2nd group.

Steelhead...What it was, what it is.....lot's of people, lot's of boats....money being spent locally, yea for some motel rooms, gas, bait, food, guide fees, turn around $$$$, tackle but major purchases....not many boats, boating accessories, motors.
