Here is a quote from the Relay for Life Grapevine website:

The American Cancer Society Relay For Life is a life-changing event that gives everyone in communities across the globe a chance to celebrate the lives of people who have battled cancer, remember loved ones lost, and fight back against the disease. At Relay, teams of people camp out at a local high school, park, or fairground and take turns walking or running around a track or path. Each team is asked to have a representative on the track at all times during the event. Because cancer never sleeps, Relays are overnight events up to 24 hours in length.

There are lots of photos and tons more information about the event at the link posted above.  This sounds looks like a wonderful event supporting an important cause.
