Rick Olson, the former mayor of McMinnville and one of Yamhill County’s three commissioners at the Wagner hearing, met me at the Red Fox Bakery downtown for a cup of coffee. McMinnville has a quirky vibe, a cultural stew of aging hippies, hipsters with man buns and young professionals who enjoy the relaxed Oregon vibe.

Each May the town celebrates its U.F.O. Festival, a weekend extravaganza with parades and costume contests. “We always say there is the Yamhill County and there is the rest of Oregon,” Mr. Olson said.

In June, the commissioners voted to uphold the appeal in favor of Mr. Momtazi and the other neighbors. Mr. Olson said he was concerned about how much water Mr. Wagner’s processing facility might use, as well as the safety of the road shared with neighbors. “We upheld the appeal based on these issues,” Mr. Olson said. “It had nothing to do with whether we like marijuana or not.” Mr. Wagner is not out of the business altogether; he can still apply for a permit to grow marijuana commercially.

The lawsuit filed against Mr. Wagner by his neighbors is pending. Mr. Wagner said the odds of being able to process at his farm are slim to none. Instead he would like to join a farm collective or find an investor to fund his operation. “No one ever really met me,” he said in an interview last week. “It’s like they act like I should go someplace else.”

Mr. Momtazi sent an email last week with one of Mr. Wagner’s deleted Instagram posts that showed the barn against a brilliant sky at sunset. “Right now I am an island of love with an ocean of fear around me,” Mr. Wagner had written. Then, he added, “#xenophobia is #venom to the #haters and those they believe they #hate #manifestdestiny #cannabiscommunity.”

Mr. Momtazi surmised that Mr. Wagner hasn’t exactly embraced them, either. Posts like that split their farm community, he wrote, “causing more hatred toward us.”
