Proudly rural, the 1,500 townspeople of Lusk often poke gentle fun at themselves, emblazoning T-shirts with phrases such as "End of the world, 12 miles. Lusk, 15 miles." You’ll see what they mean if you visit this seat of Niobrara County, whose population density averages 524 acres of prairie per person. If you find yourself traveling the main route between the Black Hills and the Colorado Rockies, a stop in this tiny burg is worth the time for a quick lesson in frontier—particularly stagecoach—history. You can also find gasoline and food, rare commodities on the open plain.
