A group of Venture scouts carry a stretcher past a group of Webelos. As the stretcher passes, the Webelos watch the scouts of the Cobras Patrol demonstrate how to treat a puncture wound. This is Disaster Day (or D-Day, if you really want to call it that). Disaster Day is a day when boy scouts from Troop 159 of Herndon hone their first-aid skills, as well as recruiting Webelos to join their troop. It is an overnight campout at Billy Goat Trail, Md., with a three-mile hike where the scouts are tasked with facing many different first-aid scenarios. Additionally, there's a bunch of first-aid stations, campfire cooking, and fun. Temperatures were below freezing that night at the campsite.
