Knowing this, I came armed with information yesterday (I'm in Music City for the National Conference of State Legislatures' annual meeting). I was looking for Metro City Hall, which is in the old Ben West Library, at 225 Polk Avenue, which is the Polk Avenue that's downtown, at the corner of Union and Polk.
Nonetheless, my cabbie was skeptical. "Polk Ave. isn't downtown," he said. "This one is," I replied.
He remained confused and agitated. "There are so many Polk streets," he said. "Why is that?"
To find the one I was talking about, he looked at his map while driving. I'm writing this, so I must have survived. I respect the 11th president of the United States as much as the next person, but Nashville could stand to show Millard Fillmore and Chester Arthur some love.
