I have a scanner installed in my vehicle, and I like to listen to various things, one of which is ATC. I occassionally travel up Interstate 81 from Mechanicsburg, PA to as far north as Greene, NY and as far south as Winchester, VA. I was wandering if anyone that is familiar with Air Traffic Control could give me the frequencies a plane would travel in if flying from Greene to Winchester. Say for instance, the exact frequencies for ZNY and ZDC that would be assigned for this section of space if a direct flight were taken. This way I wouldn't mess with programming in frequencies that I am not going to hear much in because of being too far away. I hope this makes sense, and thanks for any help.
