An ATV may be operated on the frozen surface of any public body of water as referenced in C.G.S. ch. 255, §14-387.
I didn't look up C.G.S. ch. 255, 14-387...so there might be restrictions for certain bodies of water.
And I know you probably realize that...most other fellow anglers usually are pretty cool...but then I've been around some that just drive all over including through the tip up field and I about want to start drilling a moat around my tipups to keep them away lol.
