Last weekend party buses rolled up in front of Ryan Kasper-Cook's lavish "Trista Lights" holiday display and intoxicated revelers got off. They were loud as they trampled on his neighbors' lawns angling for a view of his holiday display.

Even though, with 17,000 computerized lights synced to music, this display is hard to miss. And that came after Kasper-Cook had reached out to the bus companies and asked them to keep people inside their vehicles.

The behavior led Kasper-Cook to pull the plug on the lavish spectacular that was featured last year on ABC's "Christmas Light Fight." (It didn't win that fight.)

Hundreds come to view the nightly light shows in Minnetrista that loop every 10 to 20 minutes.

"It's disappointing because lots of people want to come and see it, but I made the right decision for the neighborhood," he said. "This was voluntary. I did it before things got out of hand."

Kasper-Cook was quick to point out that none of his neighbors complained about the increased traffic and late-night noise, and that some were even sad to see it go dark. But, he added, they also appreciated his decision.

Trista Lights started three years ago as a challenge. The computer tech by day wanted to see if he could pull off "something people have never seen before." It grew into a hobby and quickly his extravaganza gained a huge following. Photos and videos went viral on social media, which led to the national TV appearance last year. He came back with a new choreographed show this year.

The attention has brought even more people to view the show that he starts programming in September. With as many as 500 vehicles coming per night, Kasper-Cook lists rules on the "Trista Lights" website for those who stop by: No double parking, no blocking driveways, no horns or loud music and "always stay in vehicle."

Most people have followed the rules, but this year, he said, some party bus drivers have allowed people to get off the bus. The chaos and disruption "pushed things over the edge," he said.

Kasper-Cook said he heard other decorators have had similar issues.

"It's just common courtesy to be respectful," he said. "They are hooting and hollering after 9 p.m. Common sense went out the window."

While he has turned his display off for the rest of the holiday season, Kasper-Cook's handiwork is still on view at the Minnesota Landscape Arboretum where he has a small display. He also has three shows glowing in Illinois.

As for next year, "big things" are in the works, he said.

That includes an expansion at the arboretum, reviving his home show in a different location and putting up multiple shows across the metro area, maybe even one with a drive through.
