Ah! Something we have in common (I think)! Want a little story?
This tale takes place during Mrs. Prof's traveling days with the IRS (she negotiates multi-million-dollar logistics contracts and has nothing to do with taxes, in case you're getting ready to throw stones). We decided to do something fun in conjunction with one of her trips to Chicago—I would fly up there to meet her, we'd spend the night, and then we'd take a sleeper cabin on Amtrak's Texas Eagle back home. (She met me at the airport with a fantastically delicious Giordano's pizza waiting for me in the trunk of her car).
After staying overnight, we returned her car to O'Hare and walked straight to the train station beneath the airport. Now, whether or not this was a Metra station, I can't say, but we rode the train all the way downtown to the stop closest to Union Station. From there, we walked a couple of blocks, stopping for her to take the obligatory photo of Willis Tower while I watched the luggage, until we reached Union Station and checked in at the Amtrak station.
Turns out a sleeper cabin means you're traveling first class on Amtrak. We had great service, free meals in the Diner car, and just an overall wonderful trip back to Dallas.
Once we arrived at Dallas's Union Station, we took DART's rail to the Garland station, then rode a bus to the stop at the entrance to our subdivision, two blocks from our house. We were pretty stoked about that—a trip from Chicago O'Hare to our house, using public transportation the whole way. That's going to be a fond memory that we'll pass down to any grandchildren we may have.
