(1) A person commits the offense of criminal trespass onto public parks and recreational grounds if the person remains unlawfully in or upon a public park or recreational ground after a request to leave is made by any law enforcement officer, when the request is based upon violation by the person of any term of use specified on a sign or notice posted on the property, or based on violation of any term of use contained in, or the expiration of, any permit relating to the person's presence on the property.
