A "ski trip" for the junior classes where the students each pitch in money to rent out a m/hotel, get some alc and go ballistic from friday till sunday (usually). Transportation is in party buses and surely you can pay off the driver to do crazy shit on that bus.
Like the Nike slogan - Just Do It
Junior Ski Trip:
Print out a false field trip form, put a price tag on it, make ur parents sign it and give u cash, hope they dont call the school asking about it. Have fun, party, don't attract cops.
