When I was teaching, I recall a counselor telling me that one of our kids needed to attend a school in Texas because that school specialized in whatever this child required (she could not tell me).  By law, the parents were allowed one trip per month to visit for a week, and each trip cost $7500 including air fare, housing and per diem.  Services included summer months, too, so $7500 x 12 = $90,000.  And that total doesn't even include the actual cost of the services provided to the child.  It was just for the parents to visit!
