I take it you guys have never been to a house party? Because that is way too ignorant a statement to take seriously.
We live in the UK, where it is almost impossible to fit 30-40 people in a single house without being noticed, unless you're REALLY fucking rich and have a large house/mansion. See its a small country and houses down here miniscule compared to the average house in the states.
There are house parties that can practically have more than just 30-40 people depending on the size of the house, and the host can be unfamiliar with a lot of people. That doesn't mean it's impossible for someone who knows how to handle things to keep under control.
Things work differently I guess.
In all honestly, I find it difficult to imagine a single individual keeping control of 30-40 others when there is alcohol and/or smokes on offer. The likelihood of the majority getting drunk and being uncontrollable is higher and thus, so is the risk of getting caught. Generally, when you're drunk you lose perspective of any consequences and you become very noisy.
Don't know if its any different in the States, but that's at least what I'd imagine would happen when there's booze. I mean unless everyone is responsible enough to stick to a couple pints of beer and no more than that. Given that there are under-aged people involved, I very much doubt that is the case though. If it is, then I apologise for over-generalising, but I just don't see it happening.
Because I'm not from America, its hard for me to give any kind of reasoned advice any way.
