JOHNSTOWN, CAMBRIA COUNTY- Riders keep rolling into Johnstown for Thunder in the Valley. The event wraps up Sunday, but already the cleanup challenge is underway. The city hired temporary workers to cleanup for the event. Crews come in early and leave late. Organizers say it is easy to enjoy the event, but it is nice to recognize people who work hard behind the scenes. "A lot of people pitch in and it's very busy and, its hot and it's warm, so we really appreciate all the work that those people do, cause that's one of things that really helps to make our rally a success," Lisa Rager, Executive Director of Johnstown Convention and Visitors Bureau said.
