Just a head's up (I don't have a link yet), but there is usually a charity "polar bear run" through Ice the first Saturday morning of December. They encourage you to go through the exhibit in a bathing suit (and also give you a ticket to go back through later in the day fully clothed). Last year it was only $20, which is a deal, and the money goes to a good cause. We had around 20 members of the Poor Judgment Crew do it, everyone had a blast and said they'll be back this year. Something to keep in mind if you're in the area.
