Hiking with Eric and Britney of youtubes Smoky Mtn Family. Learn about the Bear Bell which chases away bears, about why the Great Smoky Mtn Park is so popular. I'm doing a few of these shorter, videos without the full narration or music on this trip because it will be a few weeks before the full feature comes out. Some of this will actually be part of our Knoxville video, but we won't show all of what is on this video in the Knoxville video, so this allows you to see more of the Alum Cave Trail.
