If you went to high school in a non-city you understand the theory of a field party. For the uninitiated, it's a party that's in a field. This field is owned by someone's parents or is just a field that's out in the country somewhere the cops don't usually venture. Nothing interesting happens in this field, it's just a place where kids can hang out without adults getting in the way. It's quite an interesting phenomenon and something everyone should do once in their lives.
