For decades, visitors willing to shell out a few extra dollars at Gettysburg National Military Park could be entertained - or bored - watching an electric light display showing troop movements in that pivotal Civil War battle.

With the opening of a new museum and visitor center that offers a bigger "wow" factor for the park's nearly 2 million yearly visitors, the National Park Service has decided that its 1960s-era electric battlefield map has outlived its usefulness.

As patrons of the new $103 million facility learn about the battle by immersing themselves in some new technology, the old center stands vacant, awaiting demolition next year. Before that happens, the 30-by-30-foot electric map inside it - embedded with more than 625 colored lights - will be dismantled and placed in storage.
