The Alzheimer's Association’s Memory Walk was held today in Portland. The event started and ended at Pioneer Courthouse Square. The Portland march is part of a national event held each year. Teams participate to raise money for Alzheimer’s research. It brings together family, friends, caregivers and concerned community members — who all want to make a difference. Since 1989, Memory Walk has raised more than $300 million nationally to help those battling Alzheimer's disease. Today's event had between 2500 and 3000 participants in Portland. It was raining, but it didn’t dampen the enthusiasm. If you would like to learn more, and possibly participate in next years event, check out this link: http://www.alz.org/index.asp
