Kids are guaranteed a scary good time aboard the USS Lexington Museum.Children 12 years and under who show up wearing their Halloween costume today through Oct. 31 will get in free. There will be plenty of treats for them on deck."This is something that's fun for kids. It's a safe, trick-or-treating environment. They come here, they have fun, and they're learning at the same time. So, we love having families onboard, and this is something, this time of year, it's fun for us to do," said Samantha Koepp-Stemplinger/Director of Marketing at the USS Lexington Museum. Another Halloween treat is the USS Lexington's "Haunting on the Blue Ghost Haunted House." It's open Fridays and Saturdays through November 2 and on Halloween night.
