If you go to Ticketmaster, tickets for tonight's Bulls/Bucks game will cost you a couple of hundred bucks tops, and that's a little more than they have demanded in the past, It's a healthy sum, but no where near as much as someone recently paid for a Bulls ticket, to a game that already happened.
There's one thing that you can say about watching the Chicago Bears play their games on TV--it's a lot cheaper than going to the game. And warmer. With better bathrooms. And cheaper food and drink.
