Landing on 4 has always been decieiving. There is always a burble of turbulence on short final. One time when they were launching off of 4, an American mad dog taxied across (in front) of the glide slope antenna. It scared the crap out of us on a 3 mile final because it caused the glide slope to dive down.
My favorite approach was shortly after Sandy: you'd shoot the ILS to 22, then circle to 13. 600' over Rikers was fun.
Waiting to depart later that day (rwy13) I swear we were about to witness a crash. One of my compatriots completely jacked up that same circling approach. Never before have I heard an accepted swear on the radio. Somebody was getting clearance from ground, and in the background you could hear "holy $&; Go-AROUND!!"
LGA is one of my favorites, as you're always entertained in one way or the other.
