Wha…… what? This is why it’s best to stay on public land. Again, blatantly false.
Assuming you live in Pa, Note the part about, “knowing that he is not licensed or privileged to do so,” followed up by the part about entering or remaining “for the purpose of” defacing or damaging the premises. The stated purpose was to fish.
(b.1) Simple trespasser.--
(1) A person commits an offense if, knowing that he is not licensed or privileged to do so, he enters or remains in any place for the purpose of:
(i) threatening or terrorizing the owner or occupant of the premises;
(ii) starting or causing to be started any fire upon the premises; or
(iii) defacing or damaging the premises.
Would have to notify you AND you refuse to leave or return at another time.
There is no scenario where you would or could be charged with trespass If where you accessed the private property is not properly posted and no other notice is given. Because it is posted in an unknown unseen portion of the property is not what the law says. Since the charge would only be a summary (ticket) this could be successfully argued in 5 minutes by a third grader but not even the dimmest cop would issue you a citation for a law that does not exist.
