I try to avoid dense cities as much as possible, but as I wander around the western states for the first time in three years, I've come to notice two things. 1). The densest places are either Dem controlled or getting that way (Phoenix) and the city planners are encouraging density with "affordable housing" because that cements their control and leads to the situation where one county controls a whole state. In this respect density is very, very bad. 2). There are many towns which have gone through a different kind of transition, e.g. Ely, NV; Salina, UT: Klamath Falls, OR. The original town center, which was small businesses, then larger ones, has collapsed and decayed and at best is a "historic center" and a whole new town has sprung up on one edge. In this situation the "nice" result is to spruce up the "historic" part, integrate it to the new town as a tourist attraction. Otherwise it becomes a slum, or is torn down for affordable housing (future sl7m).
