They call it the “Old Fashioned July 4 Celebration,” in Aspen, Colorado. This year, as usual, it featured a bicycle parade, a citywide block party, a sea of red, white, and blue, and live bands. The day’s finale, though, was anything but old-fashioned: A choreographed drone light show in the sky.

Aspen was one of many mountain towns in Colorado that decided to skip Fourth of July fireworks this year, scarred by 2018’s horrendous forest fires. “We have a red hot state,” said Pitkin County Sheriff Joe DiSalvo. “Why tempt fate?”
