By restricting admission to those under 21, Xtremes seeks to offer a safe haven for young partiers. Although there is a $12 admission fee to get in, it s a small price to pay for six hours of freedom, both for parents and kids. With off-duty police officers patrolling the club and parking lot, a staff that has passed background checks and a metal detector at the entrance, parents and patrons can have a night free of worry and anxiety.
