Sneaking out help me?

There is a party tomorrow night, the only problem is that I'm grounded as it is. Should I sneak out ? Oh and don't tell me to ask my mom instead of my dad because they are divorced and I live with my dad and his girlfriend. I don't think they'll lift it for the evening and I have to be really careful about sneaking out cause my dad is a state trooper and it sucks. I am sixteen years old.Also I'm a girl not a guy so my dad wouldn't kick my ***.
