"Have you noticed UPS-uniformed cyclists towing small trailers full of parcels in your neighborhood recently? I did a little research and discovered that they are refilling their trailers at pods strategically placed around town. The pods are refilled regularly by one of the familiar big brown trucks that used to trundle up and down the street. I think that it is rather charming to see a cyclist pedaling up the street with a trailer full of parcels, later to be seen coasting back down the hill with an empty trailer. Not only is it much more environmentally friendly, it is a whole lot quieter."
