I always liked buzzing the harbor and landing on 33R (it was about 2500') in BOS, and flying down the east river to the Statue to 29 in EWR. Of course, this was pre 9-11, not sure if they even let us do that anymore.
Ah yes, the glory days of flying for the Feds--the Federal Reserve Bank! Also, sneaking marginal VFR between TEB or EWR to LGA and crossing Central Park to land 13' taxi back to Marine Air Terminal. Is it still there?
