My regular commute is a 5 minute walk to Einstein's to sit for a while, drink a few cups of coffee and read the paper. If there's time, I can even finish the sudoku. There's a regular crowd that is there every morning and my walk back is only slightly longer because I have to be more careful carrying my coffee refill.
I'm in DC now, and the train from Silver Spring to the office this morning took 50 minutes. It usually takes 17. And it was crowded, which means it's too hard to do the sudoku with people bumping into you all the time. And there was no coffee. I don't know how people do this everyday.
