I went from Oklahoma -> Florida -> Pittsburgh -> Charlotte. As far as weather goes, Charlotte and Oklahoma provided the most variety and for me the most enjoyment when the seasons changed. However, I really don't like the Winter blues, even though it's not as a bad as Pittsburgh. Also, I can't deny that I was way healthier all year round living in Florida.
If Reacher is your first introduction to this man's acting capabilities, allow me to take the pleasure of introducing you to Blue Mountain State. All hail Thad.
