"Every single one," said Brian, who asked that his last name be withheld. He started the group about a month ago with his friend Eric, who also didn't want to give his last name.

"I grew up in the East Bay Area," Eric said. "Then I recently moved back to Oakland in February, and I just realized it's riddled with potholes."

Then one day, Eric says he had "an epiphany": he and Brian could fix the potholes.

They started with the ones they knew about and eventually started taking requests on their Instagram account. They set up a GoFundMe page where people would make donations to help them pay for asphalt.

Brian and Eric estimate they’ve raised around $6,500 and filled about 30 potholes, but they need more than just money to reach their ultimate goal of filling every pothole.

"So we decided to come up with this meetup to have the community come out and fill the potholes in their streets," Brian said.

On the Streets With the Pothole Vigilantes

On a Thursday evening in Oakland, Brian and Eric pull up next to a park with a U-Haul carrying bags of asphalt for their first "Pothole Vigilante Meetup."

People start to trickle in, loading the bags of asphalt into their cars, grabbing Pothole Vigilante T-shirts and getting quick tutorials from Eric and Brian.

"It says a lot about the culture here," said Riley Laws, who came to get tips and supplies. "Oakland isn't just a city that's just rampant with negativity. You have people there that are actually doing something."

Once it gets dark, Brian and Eric climb into a black pickup truck and head to a quiet street near Lake Merritt that they know has a lot of potholes.

"Let's get this one," Eric says as they pull on to Bellevue Avenue.
