Time to play devils advocate here.

What people are neglecting to realize here is that SW WA is nothing but small towns.
Small town people don't like out of town people cloggin the highways, making them wait in line at stores, etc.
There's a few commercial fisherman down there that don't bring in near the $$ the sporties do but they're locals and have more influence on the local politics than out of towners do.
Now if you got the idea across to the store owners and the campground owners they MIGHT be able to put some pressure on someone.
Last time I was through Cathlamet there weren't many stores that were gonna make a ton of money off of seasonal booms. I have a family member that grew up in that town and have spent alot of time in that town. An Ilwaco or Chinook it isn't.

I grew up in a ski town and hated it when winter came along. The roads were full of idiots driving way to fast or way to slow. The stores were full of rude obnoxious city people who figured you were nothing but a local hick.

It's not that I don't agree with what you're doing, I just want to show what the people you'll be pitching this to might be thinking.
