The Pennsylvania Cable Network is re-broadcasting Battlewalks from Gettysburg NPS during anniversary week.
PCN does this every year and it is an excellent program.
A camera crew is sent along with the park Rangers at Gettysburg NPS as they give a Battlewalk to park visitors.
The video is then broadcast later that day/evening on PCN.
It is almost like being at Gettysburg for the anniversary.
I would recomend it to anyone that gets PCN on their cable system.
PCN is the PA state cable network. http://www.pcntv.com/index.htm
