SAFE in Florida is basically Straight reborn, last I heard it was getting smaller but at the conference last year we had 2 SAFE parents defending the place. I met someone who spent 18 months there a couple years ago, and he described it as "a year and a half in hell"
And lastly there are hundreds of "bootcamps", Therepuetic Boarding Schools" (ie Teen Concentration camps), Rehab cults, and Wildnerness programs, most of them are so full they have to turn people away and they can charge anything they want as much as 7 thousand a month.
