Really, why would the chinese or aliens care about NJ ???
I think the Dahlgren navy labs are around there at least.
I did stay on the NJ side when I had to visit the Filthadelhia navy yard. NJ over there is preferable to that ghetto.
Why not a hotel on the airport grounds? That’s safe. Or one down in Ridley Park by the Boeing plant? I worked there 15 years. That area’s perfectly safe.
