Why would you want the expense of a place like Denver, Chicago, or Seattle? If you want to live in a ****ty suburb there are lots of better places to do it. Watching the miles of traffic jams this morning on TV drives that point home.
The actual city of Denver, on the other hand, is amazing. Walkable, vibrant, and varied. It's my favorite place on earth and it's why my wife and I choose to make our family home here.
