So much for your hopes
From the Washington Times in Benedict eases Latin Mass limits:
Officials for the Archdiocese of Washington and the dioceses of Arlington and Richmond said that they do not anticipate using the Latin Mass more often because some of their churches already offer it.
So much for allowing priests on the local level to decide for themselves (like that would ever happen).
…and I’d add, for those in Washington D.C., Arlington and Richmond, fill up your tanks. You’ll still be doing the long trek to your nearest Tridentine Rite Holy Mass.
