To kick off the two-day event showcasing a mobile 9/11 exhibit in Berea, retired firefighters from the New York Fire Department spoke with students of Farristown Middle School about the terrorist attacks that occurred almost 20 years ago. The mobile museum has travelled throughout the nation to keep the history alive about that tragic day in September. This is the first time the unit has been in Kentucky. The mobile exhibit will be set up at Farristown Middle School in Berea Thursday and is open for tours from 5 to 7 p.m. The tour is free.
