Beard, mustache, soul patch, or mutton chops—any and all facial hair will be tidied up, or shaved off, for free at a 38-foot mobile barber shop sponsored by the Wahl Clipper Corporation, which pulled up today at North Avenue Beach (1600 N. Lake Shore Dr.) for a three-day layover. Men in the military—where facial hair's scarce—can get a free haircut instead. Wahl is also collecting old razors, scissors, and trimmers for recycling, donating $10 for each item it receives to the YMCA.  Hours are 9 AM to 5 PM through Sunday. Go here for more info.
