Constructor's CommentsThis puzzle is my third-ever puzzle to be published, so I am very grateful to David for accepting it! This one was a lot of fun to make. Once I thought of the concept, I began to make a list of well-known cities with short-enough names to make the theme work and saw what phrases I could make around them. It was important to me that the cities were dead in the middle of the themers, that they were well-known, and that the themers were themselves something interesting. I am a Brit living in Canada, but the crossworld is an American-centric subculture . . . so at some point during the construction, it occurred to me that first of all, I needed to make the revealer CITY CENTER as opposed to CITY CENTRE and second, downtown is the preferred way of referring to the middle of a city in the States. I was relieved to learn, after checking, that CITY CENTRE is still a phrase people know and that the theme could work!
The fill I'm fairly happy with—I hope there's nothing that made you groan. The grid was a challenge to make smooth with that nine-letter themer in the center (/centre!) and the two twelves. It made a lot of three-letter words inevitable. Overall I'm happy with it, and I hope you enjoyed solving it!
