The event was also designed to raise money for the victims and survivors of the Aug. 4 mass shooting, where a gunman killed nine people before being killed by Dayton Police.

“The best way we can honor our fallen is by getting up better than we were before,” Chappelle told the crowd. “We won’t let those people die in vain.”

Chappelle energized the crowd and paid tribute to the strength of the region.

Tight security, large crowds

There was heavy security throughout the Oregon District Sunday.

Concertgoers had to wait in long lines to go through metal detectors.

Dayton Police Major Wendy Stiver said the community didn’t have a lot of time to prepare for such a major event.

“We’re doing the best with what we can and making it safe. We just hope people understand we are putting their safety first," she said.

Mayor Whaley said no public money was used for security expenses.

“There’s no taxpayer dollars being spent on this. The chamber of commerce and I raised the dollars for the security for here so it’s not a burden on the city at all. We’re just super grateful how generous Dave Chappelle has been on donating the stage, bringing the talent in, this is a tremendous gift to the community that he’s given,” Whaley said.

Neighbors, businesses react

Business owners in the Oregon District said Sunday’s event was important for the community in helping to heal after the mass shooting earlier this month.

“It’s reclaiming Dayton. We don’t want anybody to be scared,” said Abby Beach, whose family runs the Trolley Stop. “We want everyone to know it’s an exciting and fun-loving community.”

Amanda Hensler, co-owner of Heart Mercantile, said the store was busy on Sunday as crowds gathered for the event.

“It’s been real busy, we’re having fun,” she said. “It’s a great community, let’s keep it that way.”

Volunteer Gina Sandova, working at the donation tent, said people have really been turning out to donate to the tragedy fund.

Chappelle was also at the service Sunday morning.

“Listen, we’ve been through a tough time,” he said. “There have been tornadoes, there’s been Klan rallies, there’s been shootings — but we’re still here and we’re still strong,” Chappelle said.
