"Oak Park Art League, Oak Park. As it rounds out its first century of service, OPAL has remained a critical player in the creative culture and discourse of Oak Park. A vibrant art center with a gallery, classes and events, it's the visually-driven third of a fantastic, walkable cultural triangle along with the Frank Lloyd Wright Home & Studio and Hemingway attractions. Welcoming, staffed by incredible local artists and brimming with history, it is well worth a visit."
