The world's largest Pokémon Go gathering hits the streets of San Francisco

What began as a simple Facebook event page for friends grew into crawl with more than 9,000 people at starting points around the city and no fixed route

The largest gathering yet of Poki(C)mon Go players in San Francisco was almost a total disaster.

Up until a half hour before more than 9,000 people were supposed to begin gathering at select locations in the hometown of the viral game sensation's developer, Niantic Labs, the servers were down.
