My understanding, based on comments here and elsewhere, is that it is no longer accessible. period.
it was recently purchased from the state of VA and will be torn down or converted into commercial space sometime in the near future. the new owners re-boarded-up the windows and entrances, and built a new fence. it is only accessible through breaking-and-entering, which is inadvisable.
this is all based on second-hand info, as i haven't visited since late June '09. it was once a no-risk (short of injury) photo excursion. but now i would assume it's watched more closely and not easily entered/explored.
