(La Porte, IN) - The public is welcome to join La Porte firefighters in remembering the terrorist attacks from 21 years ago.

Firefighters will walk the stairs at Kiwanis Field until reaching over 2,000 steps, the number inside the twin towers firefighters went into to save lives before the towers collapsed.

The towers collapsed after two planes overtaken by terrorists crashed into the sides of the skyscrapers in New York City on September 11, 2001.

Firefighter Keith Weigel said citizens are invited to take part in the event on Sunday.

“There was 2,071 stairs in the twin towers, so that is what we are going to walk. That is 70 loops up and down Kiwanis,” Weigel said.

There will be food and beverages available at the event.

Kiwanis Field will open at 6:45 a.m. Weigel said there would be a ceremony at 7:20 a.m. then a half hour later, the walking of stairs would begin.
