Are you from the Bay area by chance and familiar with the goings on of BART? This seems like a significant first if it is in fact a first. I was hoping the article would have comments to see how the locals were reacting but no comments.
So glad I stayed away from BART this weekend!
The incident brings to mind previous experiences I'd had on the Pittsburg/Bay Point-San Francisco line ("Yellow" line). A group of youths would board, generally at the West Oakland station (for a San Francisco-bound train) and begin an impromptu period of entertainment (beginning with "Good Afternoon Ladies and Gentlemen") which included dancing, rap, music played on a boom box, and maybe also some gymnastics from the overhead grab bars. After the presentation, they'd ask for donations. Show over, they'd move on to the next car.
Nothing violent about this, it was mildly annoying, but it kind of makes someone used to disruption. The "performers" were never more than two or three in number.
It made me wonder if people used to these "presentations" would be more inured to the mass swarm that happened at the Coliseum station.
No, I live in Arizona. I’d remember if I had ever heard of anything like this happening, though. Maybe there’s a Freeper out there who’s more familiar with the SF area, and can tell us how people are taking this?
