I did some spot checks on the file cited above, and it's better than I
remembered. Comparing it with some of the places that I've been
meaning to return to and field-survey, it's much freer from
hallucination than TIGER. It's a bit out of date (which means both
that new development is missing and that a few abandoned roads are
there), but it's not horrible (while the TIGER-derived data are indeed
horrible).
