Tread lightly. Sidewalks are fascinating, if you look hard enough. Artist Mike McClung did, and the result is “Watch Your Step: Sidewalks,” a photographic and lost-shoe installation that examines the everyday life of a sidewalk, from shadows, patterns and debris to the social, economic and emotional imprints left behind. Through March 23. 9 a.m.-6 p.m., Arvada Center for the Arts and Humanities, 6901 Wadsworth Blvd.
