Try your hand at butchering a pumpkin today at the College of Architecture, Planning and Landscape Architecture's fourth-annual pumpkin carving extravaganza. Bring your own pumpkin, carving tools and a candle. The event begins at 5:30 p.m. at the School of Landscape Architecture. Jack-o'-lanterns are taken to Ronald McDonald House for residents to enjoy on Halloween.

Come celebrate "El Dia de Los Muertos," with the Arizona State Museum. The museum's store, Native Goods, will feature a special artist invitational display inspired by the Mexican custom.
