If you're going to be in the Chicagoland area anytime between now and March 18th, please try to get over to Lincoln Park. The DePaul University Art Museum is displaying an exhibition called "Imperial Cartographies" which is well worth seeing.
Perhaps you have an interest in history, or colonialism, or geography. Or maybe you just have an appreciation for maps as beautiful aesthetic objects in their own right. Either way, I really recommend it.
