In article om,
I've also found that if I depart IFR I"m more likely to get the
airline's runway than the GA runway at most airports.

That's certainly true at HPN. 16-34 is the big runway used by jets,
but spam cans often depart 11, mostly because it's a whole lot less
taxiing from the GA ramp. Except IFR. If you're IFR and ask to
depart 11, you'll almost always get turned down and sent to 16 or 34.
