Let's see: 7-9 rounds at 30 minutes per minimum times # of beers you can consume within each half hour = you're screwed for your course, Bri. Marc, you may want to restrict turntable selections to the start of the evening, in order to prevent damage to equipment and rare vinyl that could easily occur several beers into the proceedings. I plan to 'lay a base' by consuming a large plate of pasta every hour on the hour, along with a big glass of milk. Should get me to 9pm at least.
