On the 20th anniversary on Saturday at 7:30 a.m. there will be a memorial ceremony at the Buford Fire Tower on Lady Bird Lake.
Afterward, firefighters will head to the Pleasant Valley Drill Tower for the 9/11 Memorial Climb where they'll be in full gear and go up and down the tower in silence to equal the height of the World Trade Center.
