not in PA.
A porch party is a lot different than a house or field party,
Field parties usually involve 100s of people, kegs and at the end of the night getting busted.
House parties involve a shit load of people, illegal gambling (I won liek 250 bucks one night), cases of beer, people fucking everywhere and because we stay in a private community security hassling us after 2 AM. It takes staties 30-45 mins to get there so everyone's long gone and moved communities before they get there.
Our house parties end up 4AM field parties.
