Anywhere to park free and walk to Union Station in Chicago

[junebug]

They still had that in Glenview in 2014 when I took it to downtown then got on the Southwest Chief. I came home on the California Zephyr. The problem with Glenview was on the way home, the Zephyr was late. It didn't get into Chicago until 11pm. By the time we got to Glenview it was 12:30am. I had left my mirror light on, and the battery was dead on the car. Didn't get home until 2:00am. I always go out of Union Station now.
