This year's winner for Best Festival, the Houston Art Car Parade, is actually a weekend-long party that includes the parade; a ball; an awards ceremony and brunch; and other, slightly less official events. True to the parade's Orange Show beginnings, the celebrations are all weird, eccentric and decidedly offbeat. The procession of art cars, art bikes and what are best described as tricked-out contraptions remains the centerpiece, with more than 300 entries from across the country and an audience of 250,000 spectators at last year's parade.
