During a cold hunting season one day in 2000, Lisa Thompson stopped for lunch in a small Colorado mountain town.

“There were tons of hunters in there. Ninety-nine-point-nine percent were men,” she recalls.

Then she saw someone take off a hat.

“And her long hair comes out. I go, ‘Oh my gosh! There’s a female!’”

It was Donnelle Johnson. And ever since, the two have been close friends and colleagues, searching for game big and small every season while developing detailed hunting maps and encouraging women everywhere to join the sport. The two will be at the Colorado Springs Sportsman & Boat Expo this weekend to talk about Hunt Data, their product illustrating herd sizes across the state’s backcountry.
