Most city metro systems are pretty awesome. I even took the Blue Line to MSP. But the TC are nowhere near some cities (which is fine because it’s not nearly as big and doesn’t have awesome historic sites, Le Tour Eiffel).
However, there is one absolutely necessary thing needed when using and light rail.
I use hand sanitizer whenever I’m leaving a rail station, once I’m done touching things.
Now I’m not the most germaphobic person, but think how gross that is:
Everybody holds that pole; not everybody washes their hands; and everybody isn’t prefect and rubs their eye, picks their teeth, or whatever.
