Village Butcher at Hilltop. Can be pricey, but it is an artisan craft nowadays.

And be PREPARED TO PAY FOR PRIME....and know how to judge if you are getting prime.

Fresh market(last I remember) is the ONLY place in VAbch dealing in dry aged, if willing to make the drive, the Wholefoods at fairlakes has it all in the case, slightly greened and ready for the grill. Trim and grill goodness.
