Awesome! Small amount do indeed add up to large amounts. And as someone else mentioned, you get a couple of block walk in both directions. Research continues to show that, like dollars, even small increases in physical activity have benefit. Win/Win. Regarding coffee, maybe consider finding a brand you really like that you can brew at home (try Community Coffee based in NOLA, I order from them on line and it just shows up 1X a month on my doorstep)? Just brew a big pot at home and get a really good, large travel cup and enjoy on the train.
