It depends completely on what you enjoy spending your time doing. I personally would not want to be too far from a hockey rink, forested trail for hiking or in a state where I could not carry. Thus, I could sadly rule out quite a number of states and countries by this criteria.
Now there are other criteria too; I really do not want to be in a state which has created criteria/laws that affect my freedoms in general. Perhaps regulating my size of drinks, limiting my ability to provide for my loved ones or I definitely do not want to be in a state where one urban area dictates the political climate for the whole and vast state. I sadly do not want to be in a state that is too cold for too much of the year; thus, although Alaska appeals to me I believe their climate is a wee-bit too cold for me for the 2nd half of my century of life.
