I don't live there anymore, so can't hang out, but can talk about good things to do.
In the Colorado Springs area, Pikes peak, you can drive to the summit or take a train, also Garden of The Gods, beautiful red rock formations, you can drive through and see most of it or stop and hike.
In Denver, downtown and the mint. I'm not a big fan of their downtown, but many people like it, it has its charms. There is a nice botanical garden and the Museum of Art is great.
Boulder is great, especially the Pearl Street Mall shopping district, great restaurants, interesting shops, street performers.
Rocky Mountain National Park. Spectacular scenery, nice visitors center at the summit.
If you have more time, Coors brewery in Golden is a nice tour, also New Belgium brewery tour and celestial seasonings tea does a tour.
Many people like Casa Bonita, it's a Mexican restaurant, the food is really, really horrible but it has an arcade, cliff diving and other entertainment so the kids really like it. I'm not kidding about the food though.
