It seems this topic has gone astray and everyone is talking about moving to Colorado. So, let me warn you all. It is cold, barren, and expensive. The crime rate is high, no social life to speak of and a generally bad place to live. I recommend you stay away from here, I mean there, I mean... Oh heck, OK, its a nice place to live.
There are many nice towns and cities in Colorado. Some are cheaper than others. Unfortunately, many of these cities like Pueblo, Colorado Springs, Denver, and Ft Collins have received notice in various financial and living magazines as being places to move to. As for the expense of Boulder, why not try the south end - Manitou Springs. Now, there is a fun town suitable for many of the aging hippees that might lurk in this forum. Here are some images from the Carnivale celebration there last weekend:

Now that I have settled here I wish I could keep others out. Still, to be honest, there is no better place to live. In a recent topic started when Old Babe asked where she could move to to get away from the cold and snow, I followed all the replies. I realized for all the discomfort this winter, there is no other place I would move to. So, the Springs, Denver, Manitou, Boulder, it doesn't matter what city, any place in Colorado is better than any place outside of Colorado.
