The Rock

1: Nickname of Rikers Island. An island that contains 10 jailhouses(with the same name) and is tecnically located in the borough of the Bronx in NYC, but access is only avilable via a bridge that connects to Queens. Public transportation is avilable via the Q101R, provided by the MTA Bus company.

2: A bunch of other crap that share the same nickname and alias.

Rikers Island is a JAIL, not a PRISON.
