Here's what I know about the bus situation-

1. Nick Singer works for or is a major volunteer in the Ed Shadid Mayor Campaign.
2. He was on the phone nervously pacing around in the lobby of City Hall.
3. He then started to fill out slips for speaking before Council. I asked him who the stack of slips was for, and he said "For people who haven't arrived yet."
4. I then later went downstairs to meet the guy who was dropping off the printed materials for my presentation. While I was standing out there, a OKPS bus stopped in the middle of the street.
5. A large group of people got off of the bus. The first person to approach the curb saw me standing there and asked me "If I was Nick with Dr. Shadid's campaign."
6. I said no (and started laughing btw) and asked her what they were there for. She said "To protest against the streetcar!"
7. That's when realized that this seemed worth taking pictures of- so I started to take pictures with my iPhone.
8. I went inside and Nick was greeting them and escorting them into City Hall Chambers.
9. The fact that it was a OKPS bus freaked me out so I went upstairs to the press box and got the number for the PIO of OKPS from Kristy Yager, OKC's PIO.
10. The OKPS called me back, was perturbed, but stated that "City Church" had rented the bus.
11. Then the people spoke at council against the project.

I'd also note that some of the people who spoke weren't even OKC voters or residents.

I do not know the degree of formality of which Nick Singer is engaged by the campaign.
