Alright, I may live in San Diego but I'm actually from Vermont, so I know when it's time to turn on the heat. (The answer is usually Halloween, but exceptions have been made.) And as someone whose lived with more than a few roommates, I know that fighting over the heat bill is one of the most contentious discussions I would have each winter.
Heat bills are insane. One month, your utilities cost $50. Then the cold weather hits, the heat goes on and all of a sudden you owe $250. How the heck do you deal with such an erratic jump in expenses?
