Here’s an unusual opportunity/challenge for Aerosmith fans who are udderly devoted and thoroughly moo-tivated: a cow-milking contest, with free concert tickets to the winners. The “Get a Grip” speed-milking contest (suggested by the bovine artwork on Aerosmith’s “Get a Grip” album) starts Thursday at 8:30 a.m. at the Orange County Fairgrounds in Costa Mesa. Tickets for Aerosmith’s July 31 date at Pacific Amphitheatre and Aug. 4 show at the Great Western Forum in Inglewood will be awarded. Would-be contestants should call Don Weiner, promotions director at KNAC-FM, the contest’s sponsor, at (310) 437-0366.
