Bob Hansman (center), associate professor of architecture and artist-in-residence in the Sam Fox School of Design & Visual Arts, walks with a group of cancer survivors and Relay For Life steering committee members during the opening lap of the annual Relay For Life fund-raising event March 21 and 22. Hansman overcame malignant melanoma in the 1970s. More than 2,000 people participated in the 12-hour walk at Bushyhead Track, helping to raise more than $121,000 for the American Cancer Society. Donations will be accepted until Aug. 31 at relayforlife.org/washumo.
