Hello from the Windy City! I just checked into my hotel. I decided to try the "blue line." Well, actually it was the blue line and then the red line. It took about 1 1/4 hours. And if there was an elevator or escalator at the Grand Street station, I didn't see it. So I had to trudge up the stairs carrying my large suitcase, plus a carryon. Not sure if I'll go back to the airport the same way!
