I heard about the walk event last year when my sister called to tell me that she could no longer participate. My sister works very hard dealing with the effects of her MS. She is selfless and committed to finding a cure. Each year, instead of accepting a gift for her birthday and Christmas, she asks that we donate to the National MS Society. She is the strongest person I know, and that's why I had to get involved.
