Take a Safari to Hart Mountain National Antelope Refuge
Only the African cheetah can outpace the pronghorn, the second-fastest land animal in the world. Pronghorn spring into motion with easy grace, able to accelerate to speeds of more than 60 miles per hour. And while the cheetah might win a sprint, the pronghorn would dominate in a distance race: With a 30-foot stride and exceptional endurance, they could dust a marathon in 45 minutes.
