I should have, but we were on our way to the airport at this point, and I didn't manage to get internet access (since I had no idea what the HSBC numbers were) until that evening (Because our flight got rescheduled for the next morning) where I basically cancelled it the moment we got back to the apartment. I really should keep the number on my phone just in case.
The Chicago subway system (or the "el" as it's locally know) is made up of different colored lines (blue, green, red, pink, etc). Not racist.
