Christmas Lights at Dyker Heights. About 10 blocks, centered around the "Candy Cane House" on 84th and 12th. During the holiday season the locals bring up the most spectacular decorations-- do a Flickr or Google image search yourself and see! There's the house with the giant snowman, the house with the giant nutcrackers, the house with Winnie and Shrek, and the Toyland house with the animatronic reindeer. Go on a Friday or Saturday night, between 7 and 10. It'll put the Christmas spirit in you.
