I toured BTV as an applicant a couple years ago, seemed like a nice facility. It's an up/down, a couple mainline flights a day (generally early morning and late night) but mostly regional jets and a healthy GA/student population. There's an Air National Guard wing across the airport from the commercial terminal that flies F-16s, will be getting the F-35s in a little bit. They said there was talk of expanding the TRACON airspace to incorporate MPV, but at the moment the only satellite airport to speak of is PBG across the lake.
The town is very nice, IMHO. Burlington definitely has a college-town vibe but there are other (cheaper) places to live—Essex, Williston, farther out in Jericho/Underhill, you name it. It definitely gets cold in the winter (low teens tonight!) and skiing/outdoor activities are big here. Beautiful foliage in the fall. Not a huge amount of nightlife but there are national shows and acts that come through. What else?
