I'm happy to say that my experiences with AVP have never been anything less than acceptable. When I pass through their airspace at night while returning from Utica to Reading, their radar guys (and girls) are always friendly and sharp, just like at Reading. OK, there is a curmudgeon working at Reading, but he retires soon. The FBO at AVP waives landing fees for solo students, and Damon's sells a nice plate of ribs. I hope they re-opened after the fire.
As Andy said, I have no problem with airport improvements, as the money in the trust fund comes from the taxes I have paid on fuel. Airports like AVP will become major reliever airports for the New York area. I can see the value of a high speed rail link from AVP to Manhattan to reduce hold times and congestion at TEB and EWR. That's 50 or so years down the road, though.
Remember, things are probably worse at several fields, whatever your problem with the Authority.
