You Tube now has a collection of lectures and tours by the rangers at the Civil war battlefield s. I've been catching up on the Gettysburg ones. They are all good but Ranger Matt Atkinson is ve r entertaining as well as informative.
Is there a link to the collection?
I fortunately I can't copy and paste on the kindle, but go to You Tube and type Gettysburg nps. It also brought up some other battlefield walks. Also look at Gettysburg Remembrance parade. Every year in the closest Saturdays there is a big parade with hundreds of reenactors.
