Another one to add to the list...
155.430 CTCSS 123.0
I've heard Parks Police (Saratoga - Capital region) car to car traffic on this channel from time to time. It's also the same frequency as Columbia County Sheriff's Dispatch, but they use a CTCSS of 146.2 Hz.
Another odd one, from the past as well...
153.995 unknown CTCSS, maybe CSQ?
That frequency was my old fire department's fireground channel (Alburgh VT). One day while we were using it, a Sgt. with the NYS Parks Police (1000 Islands Region) popped up and asked us why we were on their statewide car to car channel. We calmly explained the situation and he understood, because he had never heard anyone else in the past on that channel. I don't know if it's an 'official' statewide channel for them or if it was something used in the 1000 Islands Region.
