Little sister to Piknic Electronik, Igloofest is brought to you by the same people. For 3 weekends in January (Fri-Sun), this outdoor music festival attracts hardcore partiers who come to take in electro music and drink under the night sky. Below-zero temperatures demand some serious winter layers. Many enthusiasts come in their best outlandish ski suits. There are al fresco "lounges," ice bars serving vodka and mulled wine, and even marshmallow roasting pits.
