By the way, the definition in NY State of public lewdness (a Class B misdemeanor) is as follows:
<div class='quotetop'>QUOTE </div><div class='quotemain'>NY Pen L sec. 245.00
A person is guilty of public lewdness when he intentionally exposes the private or intimate parts of his body in a lewd manner or commits any other lewd act (a) in a public place, or (
in private premises under circumstances in which he may readily be observed from either a public place or from other private premises, and with intent that he so be observed.</div>
Public place, defined in sec. 240.00 means <div class='quotetop'>QUOTE </div><div class='quotemain'>1.... a place to which the public or a substantial group of persons has access, and includes, but is not limited to, highways, transportation facilities, schools, places of amusement, parks, playgrounds, and hallways, lobbies and other portions of apartment houses and hotels not constituting rooms or apartments designed for actual residence.</div>
Transportation facility includes the entire premises of such.
While NY law is obviously not governing on Craig's case, it's basic setup is similar.
