I’ve never heard of a political rally being “fenced in” by the ralliers themselves before.
They had some kind of portable fence surrounding the entire area. Which was mostly filled by people in lawn chairs or sitting on the ground. I went after work–the attendees appeared to have been there for some time. The “gates” were attended, but I don’t know what you had to say to gain admittance. Again–I wasn’t feeling patient enough to attempt infiltration.
There were a few rent-a-cops outside the perimeter. At the restaurant/bar–overlooking the area–a guy commented that you’d see far more security at a gathering by “those” people. Wink, wink, nod, nod: Those “non-white” people. He was obviously trying to impress the young, pretty bartender with his remarks. She gave him a chilly glare but remained professional & moved to another part of the bar.
