Yeah, but unless you run a B&B or an antique store, you can't find work in Jefferson.
Richardson/Plano/Garland are still ok, for the most part. Frisco is still growing exponentially. Wylie, Sachse, Murphy Rowlett aren't far behind. Several of the folks I work with live in HEB or Grand Prairie/Arlington and points south.
North is good. Further north is ok, but Allen has some serious property tax issues. Far North Dallas proper isn't bad by any means. You probably want to stay north of Arapaho, though.
