Members of Lake Travis Fire Rescue and the Bee Cave Police Department will climb the equivalent of the 110 stories of the World Trade Center for the 9/11 Memorial Stair Climb. The walk pays tribute to first responders who lost their lives during the 9/11 attacks, marking the 16th anniversary of the attacks on the twin towers. The public is invited to attend. The climb begins at 7:45 a.m. Monday at the Hill Country Galleria, 12700 Hill Country Blvd., Parking Garage A, Bee Cave. Interested area residents can visit the Hill Country Galleria website for more details. The event was held at the same location last year.
