Colorado used to be one of the most reliably conservative states in the American West.
Then the California license plates started showing up.
A Yellowstone star just learned his new neighbors remember exactly what happened next.
Luke Grimes – who plays Kayce Dutton on the hit Paramount franchise and its spinoff Marshals – told Joe Rogan that moving to Montana from Los Angeles has not gone as smoothly as his character's life on the ranch.
His California friends drove out to visit, parked their car with California plates, and came back from a hike to find a message written in the dust: "Go back."
Grimes said he can't even go to the local bar anymore without someone itching for a fight.
"He can't wait to start a fight with me," Grimes said. "It's a win-win for him."
Luke Grimes Admitted Yellowstone Drove Californians to Montana and Locals Are Not Having It
Yellowstone wasn't just a hit TV series – it was a five-season real estate advertisement for a state that had been quietly living on its own terms.
Montana's neighbors watched that play out before. Colorado was a reliably red Western state through most of the 20th century.
Then California money poured in – cash buyers with seven-figure home equity from San Francisco and Los Angeles. By 2020, nearly 24% of all Colorado move-likely housing searches were coming from California alone, according to Redfin data.
Colorado Republicans went from controlling the legislature for decades to watching Democrats build a statehouse supermajority. City Journal put it plainly: California migration helped transform Colorado from a libertarian-leaning Western state into a solid-blue one – and now blue Colorado is turning into California.
Montana hit the same on-ramp the moment COVID-era remote workers started searching for land and sky.
In 2021 – the same year Yellowstone became must-watch television for 10 million Americans – Montana ranked second in the nation for population growth.
Bozeman median home prices have since climbed to $730,000. Whitefish hit $858,000. A single-family home in Gallatin Valley set a record at $810,000 in 2024.
Californians and Coloradans were selling million-dollar homes and arriving with all-cash offers – last year, 30% of Montana homes sold for cash, according to the Montana Association of Realtors. The Missoula mayor told a packed auditorium she couldn't afford her own home in the city she runs.
More than 85,000 Montana residents were born in California. That's 7.5% of the entire state's population.
California Moving to Montana Has Already Started Changing the Politics
Montanans fought back at the ballot box in 2024. They sent Democrat Senator Jon Tester home and handed Republicans total dominance of state government for the first time in nearly a century. The pressure isn't going away – it's organizing.
Bernie Sanders just endorsed a Democrat running for Montana's western congressional district on a platform of flipping the seat blue.
Bozeman's city commission is pushing a pro-density zoning overhaul that locals say will gut the character of their neighborhoods – the same agenda that hollowed out Denver neighborhoods, now proposed in Bozeman city hall.
The bumper stickers appeared years ago – "Montana's Full," "Don't California My Montana" – the same warning Colorado ignored until it was too late.
Grimes is not the villain here. He's a guy who fell in love with a beautiful state and moved his family there.
But a Hollywood transplant shrugging off locals as "super weird" for worrying about California plates misses what those plates represent to people who watched Denver become Portland.
That message in the dust wasn't vandalism. It was a history lesson – and Montana is desperate for someone to learn it.
