SHARPSBURG -- National Park Service employees have pretty much finished preparing for the annual fireworks celebration Saturday night at Antietam National Battlefield.
A few technicians were the only ones racing around Thursday afternoon performing sound checks on the speaker system.
Ed Wenschhof Jr., chief park ranger at Antietam National Battlefield, said the last piece of the puzzle will be laid Saturday when the Maryland Army National Guard brings in howitzers to fire during the "1812 Overture."
"That's it," he said. "All the other key pieces are in place."
Wenschhof said scaffolding was set up last week behind the Visitors Center to hold the Maryland Symphony Orchestra, which is to begin playing patriotic music at 7:30 p.m. The fireworks display will start about two hours later.
Roughly 120 employees from the National Park Service and several agencies across Washington County chalked walkways, set out dozens of trash cans and performed other tasks to help the event run more smoothly, Wenschhof said. More than 60 portable toilets were brought in earlier this week.
