Here are a couple of things that caught my attention:
This is Beacon Street in Brookline. Notice that there are separate areas reserved for walking, parking, and driving. With no cars parking on the sidewalk, Serbian-style, there is plenty of room to stroll. To provide this amount of space to pedestrians in a city like Kragujevac or Belgrade, the city authorities need to install metal posts along the curb.
Notice also the meter next to each parking space. You put coins into a slot, and a little clock tells how much time you've paid for. In Kragujevac, on the other hand, an attendant in a day-glo vest collects parking fees and tickets violators. In a post-socialist country like Serbia, the first solution to a problem is to create a government job; in the US, we prefer to invent a machine. Of course, someone has to read the meters, but the process as a whole is less labor-intensive.
I spotted this cement mixer on the campus of Simmons College. I had never before seen a piece of construction equipment painted with the lyrics to a patriotic song. If you're not familiar with the song, here's the whole text.
