People in Whitehorse are walking Sunday afternoon to raise money for amyotrophic lateral sclerosis or ALS.

The disease is also known as Lou Gerhig's disease after the baseball player who's early death brought attention to it.

Don Watt is organizing the event. "It struck my family quite hard," Watt says. "My father passed away about 28 years ago from ALS."

After Watt looked into his family's background, he discovered both his aunts passed away from ALS and probably quite a few people in the old country.

No one knows what causes ALS and there is no cure. Watt is hoping to raise at least $7500. The walk gets underway starting at noon at Shipyards Park.
