Coming from someone whos gone pretty hard and seen it all over the past 8 years or so, and had a hell of a time partying every basically weekend in high school:
-dont put anything on facebook because cops are all over that shit these days
-make sure you have and your buddies have a sufficient amount of beer/alcohol(getting it can be hard but your best bet to ask a chill college student, or a homeless guy whatevers easier) also tell people to bring their own
-Tell lots and lots of girls and get your friends to do the same and do it like 5 days before so people hear about and hype it up
-Make sure people car pool, the last thing you want is 60 cars parked in your driveway and on your road
-party proof the fuck out of the house, ive seen some crazy shit go down in parents houses
-lock your parents bed room and all bedrooms for that matter (unless your down with one of your buddies going to town on some shitfaced girl in your bed)
-dont let people drink your parents alcohol
-dont let people drive drunk, its fucking stupid and not worth the consequences
-let people pass out at your place
-if you cant find a house, a fire in the woods can be great time, drinking and camping is always awesome
-dont get arrested
and when the cops come, everyone is better off running for the hills
