That’s an anagram for “Boston T Anagram Map.” Some ingenious soul has anagrammed almost every T stop on the Boston MBTA on this handy map. Exceptions: most of the innumerable stops on the Green Line’s B and C branches, and Harvard, which rather than the lame “Hard Var” sports the rather spiffier name of “Yale.”
Note: This somehow got stuck and never published from three weeks ago, when anagrams of subway maps were hot.
