Who "fits" for a temp position  

Divorcees.  Military retireee money chasers.  Young, single guys looking for adventure.  People with marriages who don't want to be together.  Or people who know there's a base right where they want to be but there's no opening and want to get "in" by taking a temp company position until a position opens at their desired base (but beware, this can backfire if that's your strategy.

National/Regional Float positions are good for anyone who needs more cash (you'll make way more in those positions).  But beware: it will take a toll on the marriage if you do it too long.  The money's not THAT good to make it up to the wife/kids.
