I'm not playing, so this is all an outsider's viewpoint.
about 1/2 of my coworkers are into it, and holy shit are they in it deep.
2 hour walks after the shift is over (I work in a bar, so they've already been running around 8+ hours)
that just seems insane to me.
additionally, the local facebook pokemon go group had a meetup at the bar I work at tonight.
The final count of people that showed up (not all at once) was 570-ish.
fire code allows us 240.
we totally did not follow fire code.
the best part? no one really talked to each other, all faces were buried in phones.
