George, have you ever flown up the East River?

Nope.

I have enjoyed the Hudson
river VFR corridor a few times over the last year, but I have not explored
the other side. It looks to me that there really isn't one there (with La
Guardia at the north end), from what I remember of the terminal chart.

You're correct that you can't get all the way around the island. The exclusion
there is primarily for the benefit of planes using the East River seaplane base.
