I've never understood the need for hand sanitizer. It has an awful, chemical scent, and somehow dries away into nothingness, which frankly opens the door for new germs to enter the pores. But I digress. Hand sanitizer is a necessity in the summer because of subway car (or T car, i'm new remember) railings.
There's nothing more disgusting than the chemical reaction that occurs when a sweaty hand makes contact with an air conditioned metal overhead railing. The sweat instantly congeals, forming a gel of sorts between you, the railing, and the former hand holder. A virtual petri dish is instantly formed within the palm of your hand, a swimming pool of germs splashing about joyfully. And to make matters worse, once you let go, the next commuter not only picks up your germs, but the rider before you, and so on, and so on, and so on. It's a miracle we're all alive. It's no wonder city dwellers often catch the dreaded "summer cold".
That said, I'm still very pro subway/T/Metro/El whatever you must ride to get to work in the morning and home at night. I just wish the transition from hot to cold in small confined spaces could be a little less nasty!
