There used to be an air force base in Plattsburgh, so one would think it would be Liberty City of the North. (Liberty City= bar zone adjacent to Clark Field outside Manila).
Plattsburg AFB was a SAC base. On 2 occasions I had very temporary duty there. B52's flew out of there. On both occasions I noted about 30 B52 parked but ready to go on a moment's notice. Since at the time, it was US DOD policy to maintain 1/3 of fixed wing nuclear strike capability in the air at all times, there were probably a dozen or more 52's off flying over northern canada at the time. It was also a sobering thought at the time that I was within close proximity to a large number of nuclear weapons including those onboard the B52 ready to go.
All personnel on SAC bases were kept on a very tight leash and off-base activities kept to a very minimum and a "liberty city" would never have developed.
I was also at Clark AFB on several occasions and certainly did take advantage of the availability of the girls in Angels City.
As far as the rest of northern new york and new england, there is a paucity of working girls available, but if one has the time and resources, NP4P local talent can be found.
