<p>S was the party chair for a Chicago Frat. A great deal of planning goes into the parties to ensure that everyone has a good time and there is good security. He hires off-duty Chicago police officers to provide back-up while the brothers work the doors and inside. The officers help in two ways, if things get a little out oh hand they can act as calvary coming to the rescue, and they are the ones to talk to any on-duty officers who get called as a result of the party. Word also gets out that the frat hires cops, so the local police are quite "understanding." They are very protective of female partiers and try and make sure harassment of any kind is kept to a minimum. As a result, they typically have a girl to boy ratio of about 5:3. He recently quipped, "We have to be careful, otherwise we will have more girls than social skills at our parties." And yes, the beer is very cheap beer.</p>
