Now in its 25th year, the Chalk Festival at the Cleveland Museum of Art celebrates the last days of summer with beautiful works of art drawn on the walkways of the Fine Arts Garden. Taken from an Italian Renaissance tradition —where beggars recreated the works of Raphael on the plazas — the event allows you to admire the chalkworks as they progress over the course of the weekend. If you have kids, check out the Second Sunday Family Day inside the museum too. It runs from 11 a.m. to 5 p.m. today and noon to 5 p.m. tomorrow. Admission is free. (Trenholme)
