It looks like they stopped all motor traffic. What was the occasion?
Yes, they have these events, called, CicLAvia, ( a play on words, from the original events held in Bogota, Columbia, called, La Ciclovia.) where they close the streets on a Sunday, to motorized traffic, and only allow human power vehicles.
Although, they have started allowing electric bikes, which kind of defeats the original intent.
Normally, the streets of Los Angeles, are teaming with automobiles.
So, these street scenes are very unusual.
You can sure see a lot more of the city from the saddle of a bicycle.
I encourage everyone to participate in these events, wherever they are held.
