Cape-wearing superheroes of all descriptions will descend on Warrnambool on Friday to join the fight against muscular dystrophy.  A dress-up fund-raiser will be held at the Flying Horse Bar and Brewery at 6.30pm on Friday to help find a cure for the muscle-destroying disorder.  Entry to the event is by gold coin donation, with money raised going to Muscular Dystrophy Australia.  Neuromuscular disorders affect 1 in every 1000 Australians.
