The Rusty Ball has a serious side, too. The proceeds of the event (in particular, $30 of your ticket price) will be donated to charity. And even better, the money will go to the charity of your choice. A quick look at the "beneficiary list" reveals a large, diverse group of charities that will be supported by the ball. Whether you're interested in curing cancer, helping people with mental illnesses, or supporting the family members of injured or killed police officers, there's an opportunity to help a charity whose work you admire. You choose the charity your money supports at the time you purchase your ticket (or you can choose to support all of the charities).
I'm sure we'll have more on this as the Ball draws near, but I wanted to point it out so you can mark it on you calendars now, if you're so inclined.
