Having a party anytime soon? (Maybe that T-Mobile housewarming thing we just discussed?) Check out this drink calculator I found at Evite. You just enter in the amount of people that are coming, along with how long you'll be partying, and if you'll be serving wine, liquor or beer (we like all three), and if your guests are light, average or heavy drinkers (guess which category we fall under). And voila! You'll instantly know how many bottles of liquor, wine and beer to have on hand. Don't forget to collect everyone's keys at the beginning of the evening!
