While many are planning on staying in this weekend, some are bundling up and going out for fun.

Hats, coats and gloves were in play by nearly everyone, with one Detroiter offering a helpful hint - hand warmer packets.
Saturday marks the third annual Cupid Undies Run - hundreds will run one mile for charity downtown in their underwear.
