It didn't happen.
The only two people at the address given on the website were the security guard hired for the day and me.
The protest call was for 11 a.m., and just about that time, a couple of people on motorcycles rode by, and several pickup trucks drove past, but none of them stopped. I am not saying the people on or in any of those vehicles were part of a potential protest group, but based on the Facebook page of the man who called for the protest, it was on those types of vehicles I kept watch.
A bit more information below . . .
When I read Hunter's diary about the call to protest, and saw Las Vegas was listed as a proposed protest site on this map, I decided if it happened here, I would at least get photos. (On the linked map, click the Las Vegas bubble to see details.)
I got there about ten minutes early. When I walked onto the property, the security guard asked if I were "another person's first name." I told him, "No, I am AJayne" and held out my hand in introduction.
After he shook my hand, he advised me that all security cameras at the facility were in use, and that Homeland Security was keeping an eye on things. He asked that I step off the facility's private property and stay on the sidewalk. I was happy to oblige.
For the first few minutes, the security guard continued to walk around the facility's parking lot. When all remained quiet, though, he walked over near the small tree that was (thankfully) providing a bit of shade for me, and we talked for over half an hour. (I had told him I planned to be there until 11:30, just in case they came late.)
I told him how I had learned of the planned event, made sure he was aware they also called for a protest tomorrow afternoon, and offered to email the link to the map to his supervisors. He declined. He told me that "another person's first name" was his contact with Homeland Security, had all the information, and had promised to drive past the location periodically.
I spoke of my anger that someone would even call for such a protest in (what I like to see as) this primarily progressive city. He described to me the multiple incidents of vandalism to which the facility had been subjected during construction, which delayed the opening of the building more than once. (I could see all the windows had been recently - apparently - re-installed. Stickers from the glass company had not yet been removed.)
We discussed the ins and outs of "religious freedom" - me saying how amazed I am that some Americans thought it only granted freedom to them, all-the-while carrying a copy of the Constitution in their pockets - him admitting that the Muslim call-to-prayer tones sometimes irritate him, but qualified that as equivalent to living near a Catholic church with its bells ringing.
We ended up discussing homelessness, mental illness, and the government's actions where both were concerned. I can only hope he listened to the facts I provided for him about cost-effective approaches to those issues that we, as a community, are not yet smart enough to embrace.
I cannot be there tomorrow, as I will still be bowling by the (hopefully again only "supposed") 2:00 p.m. start time. I hope for a peaceful, calm Sunday for our Muslim neighbors tomorrow and every day, and that the man who called for the protest will find the peace in himself to adopt a more conciliatory attitude toward all people. . .
I left at 11:30 with my camera still in its case. All the way around, it was a decent morning.
