I think you swiped the old T passes.
Chicago has done a great job "universalizing" transit passes, 30-day passes, 3-day passes, etc. They're all pretty much the same; the computer just treats them differently.
They've got this card that gets held up to a sensor, though. I don't know what that's about.
I would love to see public transit systems create some kind of universal pass, like on the Interstate toll system for some states. Just imagine if you could use a pass for the T then use it for the 'L' a couple days later.
When I was a kid, and toilet flush levers were closer to eye level, I characterized them as "happy" and "sad", especially at my grandparents' house.
re: happy sink.
Kirk, I love you.
