We were in Garden City a few years ago during Black Bike Week. Only noticed a couple of Black Bikers who drove that far south: as far as you can go on the Oceanside road.
That said, it seems like any event organized as “blacks doing something” goes bad. Black people go to all kinds of events with no problems, but if there’s an event that’s “specially black” (or “urban” or “hip-hop”), then violence ensues.
I wonder if that’s true of other ethnicities. I know there are problems with some Latino events, like “Puerto Rican Parade” in New York, but is that an exception or a rule?
Just don't stomp their flag.
When I lived in Sacramento there was speciality ethnic/race days at the California State Fair. Every time Black day rolled around there would be news stories about shootings, stabbings, and mayhem. The people who run the Fair finally wised up and got rid of those days.
