It's Wawa Hoagie Day, part of Philadelphia's ramp up to the July 4 holiday.
Those hoagies will be marched from the Constitution Center to the lawn on Independence Mall by Wawa employees, military service members, and Independence Mall's most recognizable historical re-enactors.
The main event includes a performance by the Federal Brass from the U.S. Army Field Band, hoagie-building contests, and of course thousands of Philadelphians queueing up for a few hours for free workday hoagies.
It's a lot of work, but Morey says it's all worth it, consdering the men and women at the heart of the event.
"Our veterans, our current military, police, fire, the USO — that's what this is all about. It's about those that protect our freedom, to celebrate them," he said.
Hoagie Day is part of Wawa Welcome America celebrations, which culminate with the big party and performances on the Benjamin Franklin Parkway on Thursday.
