Ron's reply says it all... Call em 5 minutes before you enter the
area...

This is eyewash by the FAA to keep the
foam-at-the-mouth-15-second-soundbite-politicians at bay... The FAA is
actually being a GA friend on this issue (rare stance for them) by
doing as little as is politically necessary...
Push will come to shove on a gorgeous weekend, after the weather has
been scummy for weeks and everybody is desperate to go flying, and when
the GA pilot makes the request to fly up the river the controller, who
feels he is too busy, says ":Aircraft calling remain clear of my
airspace"
OK, so is the VFR corridor his airspace?
Well, according to my reading of the regs, NO...
He is not in control of the VFR airspace underneath the Class B...
The ruling issued by the FAA says, VFR aircraft must be in contact with
ATC...
He is in contact with ATC... As I read the FAR's the GA pilot says,
"Roger", dials up 1200 on his transponder, and continues on his tour of
NY...
