Marilynn Phillips says she is "cautiously optimistic" about the response of the National Park Service to her concerns about the accessibility of the new Gettysburg National Military Park Museum and Visitor Center.

In fact, the disabilities-rights activist said she may hold off on filing a complaint with the Pennsylvania Human Relations Commission if the matter is addressed soon by park officials.

Phillips visited the newly opened center last week and said she was appalled at the alleged accessibility issues. On Wednesday, however, Phillips said she was encouraged by a conversation she had with one Park Service architect who specializes in accessibility.
