There is a nice clothing optional resort in Woodstock,CT called "Solair"...you can google it online. It is a family resort so everyone from 1 day old up to 100 years old visit there
In NYS a woman can go topless in public if the intent is not salacious. So if it is a hot day and she wants to take her shirt off just as a man would, it is OK. Yeah, a woman who does that would probably be arrested for public lewdness, such an arrest would be illegal and probably make a nice discrimination suit against the municipality that did the arresting.
I'm all for the equality, I often go about my daily business with my shirt off in the summer months so why shouldn't it be acceptable for the ladies too.
