Best Cities for Singles

AOL had a nice summary of ideal cities to live in based on an article in this month's Kiplinger's. Keeping the singles' cities here because they surprised me:

1. Washington D.C.: The nation's capital boasts a diverse cultural scene, plenty of young singles and a large and growing creative class. From the hip grit of Adams-Morgan to urban villages like Bethesda, Md., and Alexandria, Va., Washington offers the best of both worlds. And don't think opportunities are just in government jobs. The area is a Mecca for tech, engineering and many other professions.
2. Denver: Denver will always be a Mecca for skiers, but there's plenty to do in all seasons: listen to jazz in City Park with the Rockies as a backdrop, check out the city's performing arts center, kayak on the Platte River, or bike the city's 450 miles of trails. City-center neighborhoods offer car-free, loft living and plenty of nightlife choices.
3. Austin, Tex.: Beer, music, tacos and barbeque add up to a laid-back scene in the capital of the Lone Star State. Young singles who stay out too late can shock their systems awake at Barton Springs Pool, the city's natural-and naturally chilly -- swimming hole.
4. Raleigh, N.C.: Raleigh offers young singles cheap housing, a variety of nightlife and southern charm with just the right mix of northern bustle. It is one of the "points" of the Research Triangle, and with three major universities in the area, Raleigh will never want for recent college grads.
5. Lexington, K.Y.: Lexington, although relatively small, offers young singles plenty of things to do: bars that cater to anyone from sports fans to gays to young socialites; live entertainment most nights of the week; art gallery hops; an opera house that brings in Broadway shows; and, of course, horse racing. Plus, the cost of living is a heck of a lot cheaper than in bigger cities.
