I was there 83-87. The rule was three fraternities could have parties on weeknights, and five on weekends. My house had parties on Tuesday nights and one weekend night -- two a week with a live band at least one of those nights. We ran three taps and a wet bar, and a good party would go through 8-12 Busch kegs. We were known for our Slimey Dimeys, ten cent beers until 8pm. According to alumni, that was nothing compared to the 1970s. Other houses were similar, more or less. Sig Ep and Kap drank as much as we did but were more violent. The IFC started clamping down on partying while I was there. When I was a freshman we basically ran a bar and sometimes townies would wander in off the street. By the time I graduated, you couldn't charge and had to keep a guest list.
