"The actions of the people 149 years ago made the site important [that anniversary day]," she said. "Knowing the stories of the men, knowing that many of them were wounded and dying ... it's an extremely humbling experience."
Favorite other park to visit: The National Mall in Washington, D.C. "I love the fact that there is so much to do, and it's free," Kostic said. If she had to pick one site at the mall, it's the Vietnam Veterans Memorial. "That's my favorite spot at the mall."
