“Thoughts and prayers are not enough.”

That’s the message Boulder resident and attorney Lindasue Smollen is paying to be displayed over Boulder and Denver in an effort to advocate for gun reform.

This comes after Boulder was the site of a devastating mass shooting last month in which 10 people were killed when a gunman opened fire at a King Soopers store on Table Mesa Drive.

“How many more senseless deaths must there be before reasonable restrictions are placed on assault style weapons?” Smollen said. “When will we have sensible gun laws?”

The two billboards went up last week, located along Highway 93, just south of the Boulder-Jefferson county line, and Interstate 25 north of Denver.

The billboards ask residents to imagine using traffic laws, technology regulations and medical care from 1791. They then read, “The Second Amendment was written in 1791. Thoughts and prayers are not enough.”

This is not the first time Smollen has used billboards to advocate for gun laws.

In 2019, Smollen paid for six billboards to be put up in Weld County after Sheriff Steve Reams said he wouldn’t honor Colorado’s new passage of the “red flag” law.

Those billboards read in part, “More Americans have died of gun violence since 1970 … than in all wars in American history.”

“Billboards are just one way that I can help raise awareness of the antiquated laws that some believe is a right,” Smollen said.

Smollen said she was inspired to use billboards by the movie “Three Billboards Outside Ebbing Missouri,” in which a mother uses the billboards to challenge authorities to solve her daughter’s murder.

Smollen has set up a GoFundMe to help fund keeping the billboards up. As of Thursday afternoon, the fundraiser has accumulated over $3,500.
