From now through April 7, your heel-toe express would be a great ride to take to and from school. The Clean Air Fiesta 2002 urges you to Give Your Car a Siesta. According to the group, nearly 70 percent of Tucson's pollution comes from vehicle exhaust. The Pima County Department of Environmental Quality, the City of Tucson and UA joined forces to bring this event to bear. More than 29 Fiesta activities are planned in coordination with the event. Entry into the program through the Department of Environmental Quality submitted before April 19 will be entered in a random drawing for prizes, including a trip for two to San Diego.

It's not Halloween, and no one wants to imitate "Eyes Wide Shut," but costumes and fun are on tap this evening when the University of Arizona Theatre Arts Department and Loews Ventana Canyon Resort, 7000 N. Resort Drive, team up to present "Theatrical Threads," a costume fashion show and benefit. Attendees get the opportunity to follow a play's costume design and makeup from the beginning, muslin drafts to the finished product. A silent auction featuring theatrical memorabilia will also take place. The show starts at 6:30 p.m. and tickets cost $150, $60 of which is tax deductible.
