You can visit the Frank Lloyd Wright Home and Studio in Oak Park on a guided tour for $20. The tour is an interesting walkthrough of a famous artists' home and methods, and a strong recommend from me. And if that isn't enough architecture for you, a walking tour is available in which you go forth to feast on further frieze-d facades on foot in the surrounding neighborhood.
These are some photos taken during that afternoon. This was also my first outing with my new Canon R5, something I had drooled over since its announcement a few months earlier. I am thrilled so far, but might cover it further once I get some more time with it.
