Don't be an a**hole. Have fun.
Those are the only rules at Snowbrawl, an annual impromptu event organized (loosely) by RedEye, Do312 and Chicagoist. What is it? One big snowball fight in Wicker Park, basically, where hundreds show up to fling powder around.
Details: 8 p.m. Wicker Park. Monday night (Feb. 17). Bring gloves. Use #snowbrawl2014 to Tweet and Instagram.
