People have been pouring into the pub at both locations since 11 a.m. People were drinking, talking, and being a community.
Inside the neighborhood establishment, every TV showed the memorial.
Outside, families shared their grief over losing the slain officer.
"You don't know what's going to happen," said CHP Officer Nicholas Ranger. "You put on your uniform, you go to work, and it could all end today."
Ranger took part in the procession.
"I was told to come down and we were just gonna raise a pint to Michael," he said. "I showed up and there's a party going on. And that's awesome."

The pub has served as a police department watering hole for years. And now, the business is giving back.
"Every penny we take today is going to the family," said co-owner Michael North.
Co-owner Owen Nolan added, "We know this family is going through a difficult time and we want to help them as much as possible."
San Jose firefighters lined up for $20 plates of barbecue. Then many stayed to help serve beer.
"Anything we can do to help them, help the family get through this horrible tragedy, that's why we're here," said San Jose Fire Department Captain Pete Roman.
Other customers bought raffle tickets or signed up for the silent auction.
Every bite, ticket, and signature was a show of support.
"We need to do this more often," said Vanessa Bravo.
Her husband is a San Jose police officer. On Thursday, she grieved for the officer's widow.
"Getting ready to go to his service this morning, I thought in my mind, I could have been her getting ready to actually be there and watch my husband in his coffin," she said.
The mood at Britannia Arms was light after a heavy and somber morning. At Thursday's memorial, friends and family had a chance to say goodbye.

North hopes to raise $50,000 for the Johnson family. An ambitious goal, but he think it's doable with the community's support. Managers said late Thursday that they've already raised tens of thousands of dollars.
"If you have a dollar and you want to come by and drop it off, we're happy to take the donation," he said.
Both Britannia Arms locations will be open until 2 a.m.
On Sunday, the San Jose Earthquakes will have a donation bin at the Easter egg hunt after their match.
A friend is organizing another fundraiser for the Johnson family, at Crossfit Moxie.
"It's organized chaos. Everyone is suffering together, working out hard together, kind of the idea that everyone is doing this together. We do it because he can't," said trainer Suzy Barr.
That fundraiser will take place April 18.
The San Jose Police Officers Association is accepting donations as well.
