HPN traffic
It has been a while since I have flown in that area but it used to be Class D airspace with the tower open something like 0600 to 2200. It is not part of the Class Bravo that wraps JFK, LGA and EWR and TEB
The airport has gotten a lot busier in the last decade and you have a mix of Corporate, Scheduled and GA in the area and on the field. You get a lot of GA traffic skirting around the NY Bravo going over or near HPN. The article is crap but I suspect there is a lot of maneuvering done on a regular basis to avoid conflicts.
NYC controllers will usually give you flight following and shortcuts which is well worth doing given the amount of traffic in the area. (BTW - NY controllers are on the whole very friendly and helpful to GA. Just do what they say and shortcuts materialize. No excuse not to use them)
