What's wrong with Staten Island into Manhattan? There's both historical precedent and a heavily used ferry.
Yep, there is a clear community of interest of ferry riders. Many thousands of Bronz's NYPD officers ride the ferry in from Staten Island to Manhattan every day, where they police Times Square and make sure no terrorist attacks occur. So if you disrespect that community of interest, then you are disrespecting the police and helping the terrorists win.
I know you meant to say 'Bronx', but this was too funny to pass up....
