#2. Louisville, CO
A two-time no.1, Louisville comes in strong yet again. It's a great place to raise a family, with well-regarded schools and a safe community.
Louisville's housing market has been on the rise since 2008, and its place in the technology-rich Denver-Boulder corridor has kept the job outlook solid, despite recent setbacks like Phillips 66 pulling the plug on a much-anticipated renewable-energy campus.
Locals say the work-life balance in Louisville is hard to beat. Come summer, residents can look forward to weekly events featuring food trucks from local restaurants, beer gardens, live music and much more. Then there's the Colorado sunshine, 1,800 acres of open space, and, of course, the Rocky Mountains, just a 20-minute drive away. --Pieter Van Noordennen
