My husband and I moved here a year ago from Seattle and found ourselves in Highlands Ranch. Having 3 small children, I have never seen a place more dedicated to children than here. We have opted to stay here even though his airline lost the base here. He would rather commute than move the children from here. You should look here and take a good look at the 4 huge community centers and all they have to offer for kids. The only other place I would like to live is Boulder...bet the location we would want to live is too much $$$. Good Luck...and don't rule out HR. I have found it easy, as a mother not knowing anyone who is alone often, to make friends...and genuine friends.

BTW...it is only 45 minutes to the airport. Either the toll road...no traffic or highway.
