This article describes the problems in Baltimore with privatizing recreational centers.
Here's a quote:
Baltimore Mayor Stephanie Rawlings-Blake is getting a lesson in one of the major downsides of privatizing government services: When you ask outside groups to take over something the city has always done, their agendas won't always be the same as yours. That's what's happening with the mayor's plan to privatize some of Baltimore's recreation centers. One of the nonprofits that is bidding to take over two centers would provide programs not just for the kids that have traditionally been the rec centers' focus but also ex-criminal offenders and psychiatric patients. Another group seeking to take over two other centers would charge fees for the use of the facility, ranging from $30 a year for evening basketball and dance programs to $75 a week for summer camp.
