Hello, what is the reason that you changed Bennington from place=town to place=city?

The place=* tag is to indicate the regional importance of a place rather than denoting its incorporation status. The entire Town of Bennington has a population of only ~15,000 people, putting it firmly in the place=town category, even if it is the largest town in this region of southern Vermont.
