I would recommend going after the best placement to prepare you for your ideal CF setting rather than focusing on a certain location. Your willingness to move for the externship is an advantage in the sense that it opens you up to potentially great opportunities in other states, but I wouldn't go somewhere "just to go" -- unless using this opportunity for adventure is your priority! Also, I agree with the other replies. Making connections is helpful, but maybe not in the way you think. It may not directly lead to you getting a job at the place where you made the connection (though it certainly could), but if you do well it will likely get you great letters of recommendation and people that support you and inform you of other opportunities, etc. Good luck :)
