I went to Chicago’s Museum of Contemporary Art today. It’s only free on Tuesdays. Today being Thursday, you’re supposed to pay. When you pay, you get a little metal button to wear. It’s not a pin, but a clip-on button, so they can fall off kinda easily.
When walking up to the MCA, I always scope out the sidewalks and curbs for any fallen buttons that let me get into the museum for free. In fact, a lot of my time in the museum is spent looking for these buttons. It’s like a fun game. You can walk around without the buttons and the guards don’t say anything. It’s more for the treasure hunt challenge.
