Northwest airports near flyfishing spots

Hi Everyone,

I am looking for good flyfishing locations around
Washington/Oregon/Idaho/Montana/Vancouver BC.

It would be ideal if the airport was either walking distance to the fishing
holes, or there is some type of shuttle or taxi service that could be
purchased.

I would either rent a 182 or piper warrior/arrow for the trips depending on
runway stats and other pertinent specs. One of the rental outfits I use
doesn't allow their aircraft to land on non-paved runways, so that has an
effect also.

Any help greatly appreciated.
