The closest public use airport to Ridgefield would be either Woodland State or Goheen. Woodland State is right off of I5. No hangars and I am uncertain of its tie down situation. I drive by it often and see an odd airplane or two tied down.
Goheen has tie downs in the grass. Check with the FBO (such that it is.) There are private hangars there but most, if not all, are full up (like mine with junk!).
Your best bet for any kind of hangar space would be Pearson. Call the FBO and see what they may or may not have. It is about 20 minutes drive to Ridgefield, depending on where in Ridgefield you are going. It is a tiny town but a very large city by square miles. It runs from East of I5 all the way to the Columbia River.
If you are touring with the airplane, there are many great places to visit. Several Aviation Musuems, coastal towns, etc....
