I guess my ignorance is showing. I didn’t know there was a Mount Rainier in Washington DC, and I assumed the map was referring to the Mount Rainier I see every day driving to work in Seattle.
I wonder how the naming order went, and if it’s a coincidence or intentionally doubled name between the two Washingtons.
Whenever I hear about news out of “Washington” (Rarely, I only really deal with local sources) I used to get tripped up. Now I’ve come to realize that important news never comes from Washington state unless it’s about Boeing, Microsoft or pot. And then Microsoft is usually referred to as Redmond.
