Stacie Lenar, 37, of Highlands Ranch, said she has never taken an interest in politics, but rather “left that up to other people.”

In the wake of recent school shootings, Lenar, the mother of two small children who are entering the public school system, said she can't be complacent any longer. Lenar joined thousands of people March 24 at Denver's Civic Center Park for the March for Our Lives to protest gun violence and spent time wandering the crowd signing people up to vote.

“I never really got involved, but gun violence really hit home for me after a friend of mine in Florida was murdered by her ex-husband,” Lenar said.

Lenar joined the Highlands Ranch group Moms Demand Action, and has vowed to fight for better gun laws and safer school policies for her children.

“I fell like there are a lot of things we can do that don't tread on the Second Amendment,” she said. “It's horrifying to send my kids to school. We love the public schools and want to support them, but I have to care more about innocent kids over that violent guy's right to own a gun.”

There are no clear estimates as to how many people showed up to the rally, but streets were filled to capacity for several hours as protesters poured into Civic Center Park, before marching around town holding signs and chanting “Vote them out, vote them out" — a reference to lawmakers who oppose changing gun laws.

The crowd heard from local officials and activists, and booths were set up offering people the chance to register to vote. Music blasted through the park, and some families held picnics with small children, while enterprising Girl Scouts sold cookies.

The unified purpose of the march was to let lawmakers know the people of Denver have had “enough,” attendees said, but some people came with a specific purpose in mind.

Senior citizens and infants were among those in the crowd, joined by others in wheelchairs, in strollers and some on roller skates. Students of all ages carried signs calling for their safety, and imploring adults in government to hear their pleas.

Students Catherine Stevens, 9, and her brother Drew, 7, carried a handmade sign that said “Guns don't kill…umm, wait, they do.” Catherine said she put a lot of effort into the sign for the march.

Their mother Alissa Stevens, said it brought tears to her eyes that today's kids live in fear, and seeing so many people come out to support them.

Father Nick Stevens took a harder stance when it came to fighting for his kids' safety.

“It's time to overturn the Second Amendment ...,” Stevens said.

Meanwhile, Tom Seagroves said he thinks there can definitely be some middle ground that makes the Unites States safer, without treading on gun owners' rights.

“I'm a hunter, and I hunted with my father, so I don't like the idea of raising the general age (of gun ownership) to 21,” said Seagroves. “But we have no reason for assault rifles. They're not used for hunting."
