Hundreds of rolling artworks take over Allen Parkway and downtown for the fortieth Houston Art Car Parade, a free spectacle built from imagination, welding, paint, lights, found objects, costumes, and wonderfully impractical ideas. Entries range from transformed everyday vehicles to moving sculptures that look as if they escaped another planet. Stake out a curbside view, watch artists and neighborhood crews roll past, and celebrate the stubborn Houston belief that creative expression should be.
