Well I'll drop the attitude if you want drop the attitude too and recognize I was asking a general question not pertaining to specific area in "upstate" NY or really having specifics other than generalized to see if it's worth using. And seeing 50 years ago is along time and technology changes.
OK. My experience up here in the southern Adirondacks is that GMRS is just plain non-existant. There's a REACT group in Saratoga area that has a repeater and won't share the channel with anyone outside their group. I don't monitor their channel so I can't even say if they're still active.
There's some activity in the Rochester area, but it's hit and miss. Albany area has a couple of listed repeaters, but again, no significant activity. The Adirondacks are pretty quiet although you'll hear some occasional FRS activity in many of the campgrounds, mostly kids or occasionally folks talking their rigs into campsites. I've driven the Thruway from Albany to Rochester and back many times with a scanner running on all 22 GMRS/FRS frequencies with dead silence even going through populated areas like Utica and Syracuse.
I can't speak for other areas of the state but if you're interested in a specific area or areas, others may be able to offer their insights.
As extensively discussed over on MYGMRS.com, GMRS as a chat hobby is generally disappointing in many places. Most folks get into GMRS for family or group use. Groups like off-road clubs like it because it's reasonably private and, if you use commercial grade gear, very high quality communications subject to the usual limitations of UHF. If you're not aware, Jeep has partnered with Midland and designated GMRS as their preferred communications platform for Jeep Jamboree and other off-road events.
At $35 for a ten year family license, GMRS is a pretty good bargain. My wife and I use the upper high power channels for camping convoys and in-camp communications (cell service stinks where we camp so reliable two-way radio is extra valuable to us.) I have enough Motorola gear (Commercial and Professional Series, not the FRS/GMRS talkies) for anyone who joins us.
