I don't like tenting in the rain.... But, I can appreciate wanting to spend the money fishing. If you want facilities there is a State Park on the Bogi right off of 101. I thought I'd drag my trailer over there a time or two. But, I like to fish on the way back, and a trailer would limit where I could go.

There is also camping along the Hoh, Oxbow, Cottonwood, and up in the park too.

I guess it depends on how much you want to rough it. I guess I'd bring a big blue tarp to help keep the tent dry.
