The indoor shooting range at Archery in the Wild in northern Colorado used to be dominated by camouflage and hunters. But on this Saturday morning, the archery range is dotted with ponytails and 7-year-old girls like Y'Jazzmin Christopher.

The popularity of The Hunger Games series is fueling an interest in the sport of archery, particularly among girls. Some sporting equipment outfitters say they've seen a big boost in bow and arrow sales since the film series began in 2012.

The 2013 election marked a victory for foes of hydraulic fracturing, or fracking, in Colorado. Voters in three Front Range communities decided to put limits on the practice.

The heavy floodwaters in Colorado this month caused more than 37,000 gallons of oil to spill into or near rivers, and the state's oil and gas industry is rushing to fix equipment damaged during the storm. It comes at a time when there's growing public concern about the environmental effects of hydraulic fracturing in the state.

The rambling, funky ride called Banjo Billy's Bus Tours, in Boulder, Colo., is equal parts history, crime stories and comedy. It's all woven together by John Georgis — better known as Banjo Billy — in a playful, "choose your own adventure" style.

"You can either choose a PG tour, or a PG-13 tour, or an R-rated tour," he tells one group of riders. The crowd chooses the R-rated version, but they have to work for it.

"If you want the R-rated tour, you gotta say it like a pirate," Banjo says, drawing a bunch of "arrrrghs" from tour-goers. "R it is!"
