According to this article, my present residence is #2 on the list of America's best-read cities. I can buy that; in addition to the Barnes & Noble at Potomac Yards, there's quite a few used book stores around Old Town and the other neighborhoods, and the city library compares well with the system in Minneapolis - quite aside from not having to merge with Fairfax County, as MPL had to do with Hennepin County.
I do like the comment here about why Cambridge is #1. Hint: it has nothing to do with Harvard. :)
