August 4, 2022 KEEP BACK 343 FEET –  When following a Lake St. Louis Fire Truck. Why that odd number? That number is a memorial to the 343 fire fighters who died in the line-of-duty when the World Trade Center Towers collapsed on 9/11.  What a humbling memorial and a reminder of the dangers facing all first responders as they serve our community.  Please think about all the men and women serving us next time you’re behind a Lake St. Louis Fire Truck and are cautioned to Keep Back – 343 Feet.

Original Title: TIL that the Lake St. Louis, Missouri fire department displays “Keep Back 343 Feet” on the back of their fire trucks not only as a safety reminder, but specifically in remembrance of the 343 firefighters lost on 9/11.
