The group from Portland, which includes numerous other relatives, is known as "Aiden's A Team," in support of Darling, whom was diagnosed at age 6 with Charcot-Marie-Tooth disease, a nerve-related disorder that causes muscle atrophy. According to MDA New England Regional Coordinator Jill Marshall, the walk was expected to draw about 150 people and raise about $20,000.
