If you are in the area and want to see some awesome art, don't be boring and go to the Baltimore Museum of Art. Yes, they can have interesting stuff but the American Visionary Art Museum has just got so much more! Also, their gift shop is great in terms of prices and amazingness. And then, when you've exhausted yourself from looking at everything, you can go to the BMA and have fun there!
I wish I could have taken photos inside the museum but it wasn't allowed. There was a wedding about to happen there which I think is far more original than just getting married on the side of the harbor.
They also had some really great entries from the Baltimore Kinetic Sculpture Race which happens every May.
