Is your social life feeling lifeless? Make it positively undead this weekend at ZombieWalk Columbus. Meet in Goodale Park on Saturday, May 12 at 4 p.m. — in zombie costume and makeup — and take an entertaining traipse through the Short North. Bring canned food to donate; the event benefits the Mid-Ohio Foodbank and the Leukemia and Lymphoma Society. From 10 a.m.-3 p.m., special-effects makeup artists at Rendezvous Salon, 2600 N. High St., Campus, will help you look your worst.
