This is now: Main Street has stepped up its style with cheaper digs than Boulder and a growing high-tech scene.
Where is it?: Next door to Boulder, off U.S. 36
How to say it: Loo-us-ville, not Loo-ey-ville
The vibe: According to restaurant owner Jim Cohen, "Everyone knows everyone, and people are all friends."
43 percent: A Boulder home is that much more expensive than a Louisville one.
The new top dog: Look for scientists and techies when energy giant ConocoPhillips opens its alternative-energy research center in summer, 2013.
Culture club: Check out the Art Underground's open-studio space just off Front Street for dance classes, theater, and workshops. (theartunderground.org)
