When we retired, we had to decide whether to move or stay put, and we decided to stay where we were. So I guess we actually did choose to live in our pleasant but unremarkable city of 30,000, about 30 km. from Boston.

It's very dangerous to make decisions based on vacations, but I have to say that we were absolutely delighted by the city of Boulder, Colorado. We spent a couple of weeks there when our son was going to the University of Colorado. If you told me that I had to move, and that I had twenty seconds to name a city to move to, I'd name Boulder, Colorado.
