At about 5:20 yesterday afternoon, I boarded a DART train downtown and sat behind an out-of-towner who said the following to her travel companion: “Have you noticed how clean this city is? It’s so beautiful. Everything is so picked up. … And there’s no homeless people accosting you. It’s nice. … Look at this. There’s no trash. Do they have people sweep up every night? … And the people are all so friendly. It’s cool.” She was so effusive with her praise for our fair city, the man she was with could hardly get a word in.
