Now that the plotline is actually in progress, this seems a little late, but I've got two questions:
1. Absolutely no bridges/tunnels-not even to New Jersey, Bronx, Queens, Brooklyn (Almost wrote Broker there

)? Or do we get to have our dinos explore the whole of NYC?
2. Absolutely no humans-not even half-insane cannibals living on the subway/in relatively well stocked bunkers?
It's you and me against the world. We attack at dawn.
This is the way the world ends. Not with a bang but with a whimper. - T.S. Eliot
