Our plan for the day was to drive from Nehalem Bay State Park to Cape Lookout State Park, with some stops along the way to do some birding. It was cold and foggy so we were in more of an exploring mode. As we crossed the Nehalem River, Jeanette noticed a sign pointing to a dump station. We decided to explore, and were surprised to find it located at a water treatment plant.
I have a distaste for water treatment plants, aka sewage treatment plants, especially for birding. And they can be difficult to bird because of fencing and locked gates. So when I saw this sign "Bird Watchers Welcome", I had to take a look.
