The original poster was suggesting that you request traffic
advisories while under the class-B floor.

I've flown under the NYC Class B floor along the beach several times, You can
tal to Kennedy tower but they've never done more than acknowlege the call.

One day I started thinking about the wake turbulence of the Airbuses & 747"s
passing 500' above me as they land on 33L&R & haven't flown below the floor
since.
It's just too easy to get clearance through the Class B
