bringing Madtown to B'Quilla...

My roommates and I will be hosting the final stop of the so-called traveling Halloween party next weekend. If the weather and the porteros cooperate, it will be on the rooftop of our building, which provides one of the most amazing views of the city at night. This is going to be the party that the whole town will be talking about. I have already bragged to everyone, Gringos and Colombians alike, that I am from the home of the best Halloween party in the world. Which means that I have a reputation to live up to and need a kick-ass idea for a costume. Pronto. Ragstock is no longer a couple blocks away, so creativity is a must. Group themed or solo, any and all suggestions are welcome.
