Fort Collins, Colo.
More than 30 miles of bike roads. And roads is exactly the right word. Ft. Collins has many miles of separate, paved roads for bikers. It's as good a symbol as any for the way citizens of this small Rocky Mountain city (population: 144,000) see themselves. Summers are for biking, hiking, camping, golfing, and boating on 1,900-acre Horsetooth Reservoir, which sits at an elevation of 5,430 feet in the foothills. Winters are for skiing, snowshoeing, and partaking of the product of the city's highly regarded microbreweries. Median home price is $221,400.
An easy 70-mile drive gets you to Denver International Airport and a wide variety of cultural venues. Not to mention the MLB Colorado Rockies, the NFL Denver Broncos, the NBA Denver Nuggets, and the NHL Colorado Avalanche.
