I just returned from a visit to my state capital
in Harrisburg, PA.  I was a little surprised to see a row of six or
seven Trifoliate oranges about 6 feet high growing along the south side
of the capitol building with no special protection.  There was no
obvious winter damage I could see and the plants were blooming. 
This should be right in the middle of USDA zone 6.   

Several years ago I also saw one growing in Philadelphia, near Betsy
Ross's house.  This is significantly warmer and the site was very
protected from wind.  Michael Dirr's book on Hardy Trees and Shrubs
mentions them being grown in Boston as well.
