So I just realized I instinctively put "house party" in the title,when I really meant "party at my house" which is actually an apartment. Albeit a big apartment, but an apartment nonetheless.
Our neighbors throw similarly sized parties almost every other weekend, with tons of drunk chicks yelling like banshees out on the front porch, and they've never had the cops called, so im not too worried about that, I am def gonna be knocking on all of my neighbors doors to give them my contact info, etc. tho just in case.
Also, my roommate owns a pretty sizeable keg and bucket, but its missing the pump thing, anyone know how much one of those runs for and where to get it?
