Halloween?

[johnnie-b.livejournal.com]

Hey everyone, I was looking for something to do the weekend before Halloween (so the 27th/28th/29th) and I was hoping maybe some of you all would have good suggestions for something fun to do in Cambridge/Somerville/Boston. Basically, I'm looking for an excuse to wear a costume and have a good time. If it's like a club-night or event with dancing or what have you that it be gay or gay-friendly, as I will be dragging my halloween-resistant boyfriend to it :-D

Thanks for any suggestions. It's my first Halloween in the city, and it's my favorite holiday so I want to do it up right!
