Atlanta's Trop 74, chartered to St. Philip's Episcopal Church in Buckhead, received a preview of a new video being produced by the Boy Scouts of America.  Author Alvin Townley, who is featured in the video and conducted the interviews of other Eagle Scouts, shared his story with a Scout Hut packed with Scouts and parents.  Before an extended question and answer session began, Alvin showed a rough cut of the video to the Scouts.  The production focused on five Eagle Scouts included in Alvin's upcoming book, Spirit of Adventure.  The video will be shown to more than 2,500 people at the National Meeting of the Boy Scouts of America and will be available on AlvinTownley.com and through the National Council of the Boy Scouts.
