A group of kids from the Boys and Girls Club of Prince William County take a look at a 10 pound Parrot Rifle at Camp Manassas near Jennie Dean Elementary School, in Manassas, Va., Thursday, July 21, 2011. DeAngelo and his friends were camping at Camp Manassas near Jennie Dean Elementary School and were dressed as a Confederate Artillery Unit. The Parrot Rifle was capable of hitting targets a mile and a half away, according to Mike DeAngelo, who is a living historian camping out for the weekend. This particular cannon they were using was used in the Civil War movie "Gods and Generals." (Drew Angerer/The Washington Times)
