It reminded me of a trip I took on Max earlier in the summer, and there was a dog on the train taking up a seat.
On the same trip, strange but not illegal, a young man entered the train holding his pants up as he walked. Of course, low slung pants are the style nowadays, but the young man had chosen blue shorts with stars, and so it kind of stood out. And he was wearing his pants slung so low there was no way to keep them up except hold them if he walked any distance at all. What kids endure to be stylish.
Finally, there is the downtown church that wants everyone to feel comfortable using their restrooms. However, I didn't see any street people using the restrooms or other very nice meeting room facilities. So, maybe the restrooms are only for certain people who identify. You can't make these things up.
