Pokémon Go as a source of good for communities
There's a lot of reasons I like this game, but one of the most awesome ones is seeing people (including groups of friends and whole families) out and active in the neighborhood.
And if you haven't considered it yet, they're also a crime deterrent. At the same time, they're potentially vulnerable to those who would take advantage of them.
So if you see folks walking about with thier phones out at all hours, greet them and ask them what team they're on. Be nice to them.
If you're a player and see something suspicious, stop and call the cops.
This game can be a HUGE source of good for everyone.
