Yesterday we heard from Brooklynite Mariela Quintana on the ins and outs of a brownstone Halloween. Today, Upper West Sider Eliza Shapiro weighs in on a more local type of trick-or-treating.

Mastering the art of a successful Upper West Side Halloween is a subtle craft indeed. The UWS proper (not truly Morningside Heights, mind you) is certainly not the ideal neighborhood for a college student: you will have maneuver roving bands of 11-year-old candy-fiends on Friday night. However, should you decide to venture below 110^th Street but still stay local, there is much neighborhood fun to be had this Hallows Eve.

Scoff all you want, if one was truly dedicated to some form of trick-or-treating, the Upper West is the place for it. If your slutty nurse costume is too revealing to gain to access to the treasure troves of huge apartment buildings on Riverside and West End, fear not. Costumed or not, just walk along Broadway from the 80's-100's and be on the lookout for stores giving out candy: Bwog recommends heading to the bodegas and older neighborhood places and then to Amsterdam and Columbus and following the same protocol.

It's never too late to rediscover your passion for trick-or-treating. For those of your new to New York (or new to post-adolescent trick-or-treating), Brooklyn native Mariela Quintana has the scoop on the borough's best locations, as well as tips and tricks for uncovering the best candy. Tomorrow we'll hear from Upper West Sider Eliza Shapiro.

It would be impossible to attempt to tackle every neighborhood in the borough of Brooklyn in one night, so here is a survey of some of its most noteworthy Halloween destinations.

Essentially, Brooklyn Heights is the Greenwich, CT of the borough. On nearly every residential block you'll find Saab station wagons double-parked outside of brownstones unloading gaggles of boys and girls clad in tennis whites. Although the WASP-factor is unusually high for a Brooklyn neighborhood, the affluence and family-orientation of the Heights' residents lends itself to Halloween. The best block to hit up is the lovely, entirely residential Garden Place. There is little traffic here because the street is only a block-long, which gives it a members-only feel.

Chabad is the new place in Harlem for singles to meet and "schmooze". Seriously, it beats 1020.

Coming soon in theaters, Checkmate at 112^th Street. You never knew a bishop could be so dangerous.

Why don't you just go to Africa and save some lives like our "celebrated economist" tells us to? Phelps and Stiglitz are in the next room, kind of ticked off.

You can't get into Barnard because of failed mercantilism? Bwog is just itching to protest the Columbia-Barnard Free Trade Agreement.

All the world's a stage! Know thyself! At least before you go trick-or-treating...

Bwog kicks off Halloween early this year with a special guide to two of the neighborhood's best costume purveyors, Ricky's and Possibilities @ Columbia.

You can divide the world in two camps: Those who love Halloween and those who hate it. Bwog falls into the former camp and we hope you do too. But we understand, fun is not for everyone. If you're a Halloween hater, a self-conscious self-customer or just not in the spirit yet, Bwog's here to help. Today, we're guiding you through two of Morningside Heights' most unabashed Halloween haunts, the already infamous Ricky's and Possibilities@Columbia.

The ghosts and ghouls come out on All Hallow's Eve, but All Hallow's day is ruled by campus groups. The Statement of Principles, in development since the Minutemen aftermath, (and reproduced here after the jump) was unveiled and has been covered in signatures, while the deans have set up a trick or treat stand and are passing out cupcakes.

Down on college walk, the Rotaract Club is selling Cuban food, while the Columbia Musical Theater Society is having a classic bake sale. Meanwhile, the Word Wall is gathering more language. And what would Halloween be without a little blood? New York Blood Center is taking donations today. Vee vant to suck your blood (through a tube, so we can give it to medical patients.)

From now until 5, every RA in Hartley and Wallach is giving out candy at their doors to trick or treaters.

Thanks Halloween for giving us another reason to visit the LLC besides getting that key replaced!
