Did they say Western PA or the West Shore?

It sounds like you’re parked in a shared lot? Are you a minor? If not are you on the lease? If not, you’re not a tenant. At best you’re a guest and at worst an illegal occupant. In either case (legally a tenant or a guest) if the landlord says no, don’t. If they hear from another tenant about loitering and decide to call the cops, do you want to be the test case?

TLDR: if you make someone uncomfortable doing it, you’re loitering. If they call the cops and you refuse to to leave, you’re going to jail for disturbing the peace.

§ 6-202 Conduct Prohibited. [Ord. 996-7, 6/14/1999] 1. It shall be unlawful for an individual or for groups of two or more persons, regardless of age, to congregate on or in streets, parks, public or private buildings, places of amusement or public or private places to which the owner or tenant has not given consent in the Borough of Red Lion at any time if those persons are causing alarm, danger, or discomfort to the inhabitants of the Borough or users of Borough thoroughfares or sidewalks, public parks and public or private places or buildings by creating a breach of the peace or a danger of the breach of the peace, the obstruction of pedestrians or vehicles, any disturbance or alarm to the comfort or repose of any person, or the obstruction, harassment or interference of any person lawfully in any such street, park, public or private building, place of amusement or public or private place or sidewalk. This section shall be in addition to other conduct prohibited elsewhere in this Code of Ordinances and in Chapter 55 of the Pennsylvania Crimes Code, 18 Pa.C.S.A. § 5501 et seq. and, specifically, § 5503 (disorderly conduct), § 5505 (public drunkenness) and § 5507 (obstructing highways and other public passages). This conduct shall not prevent or prohibit the congregation of two or more persons for purposes of lawful assembly or for purposes otherwise protected by the Constitutions of the United States of America and the Commonwealth of Pennsylvania or to prohibit peaceful picketing in the case of labor disputes or in the exercise of the constitutional right of assembly so long as such activity does not otherwise constitute a breach of this section.

You don’t have to choose either of your last names or any last name at all for the child, but it could complicate matters where you’ll have to constantly prove they’re your child. You can choose to hyphenate all your names together if you want. Choosing just Eagles is fine. However being named “Jason Kelce Green-Philly-Eagles” would be pretty fucking awesome.

Legally, if there’s no barrier to entry and no signage it’s not trespassing until you tell them not to enter your property yourself. At that point if they re enter your property, it’s trespassing. Put up signs and do the purple markers between them. Most responsible ATVers respect that sort of thing.
