It is absolutely insane how many people play this. Me included.
Me and some friends were at a park in Seattle, late at night, and my friend goes "Oh shit, an Eevee!" and some disembodied voice in the darkness goes "Where!?"
Long story short, we met like 30 people in the park spaced out over an hour, all playing Pokemon Go. Walked with some lady we met in the park, catching Hitmonlees. We walked back to our cars, saw people playing Pokemon Go. Some Chinese old couple saw us and laughed, said something in Mandarin, and waved their phone. I don't understand Mandarin, but they were probably playing Pokemon Go. Driving back home 12 A.M., saw people walking around playing Pokemon Go.
This is the greatest social experiment ever.
