Real Life Warnings & PrecautionsOne last side note of a tip, and this goes out to all Pokemon Go Players, is to be safe while playing (as Pokemon GO will do with every time the game starts up). Don't try to Pokemon GO and Drive, not even in residential areas without first pulling over. Just like how eating and drinking while trying to drive, so Pokemon GO can cause as great of a distraction to drivers across the world.
Also, don't trespass on private property, even if someone has a Charizard, Dragonite or Snorlax in their backyard. And remember to watch out for scammers trying to lure you to a certain location, like what happened to a number of people in Missouri that weren't prepared. Niantic has already released patches to help fix privacy concerns, but there will always be some that will try to trick others (especially with Lure Modules).
With that being said, watch out for other certain characters when walking down the street and don't put yourself in harm's way. Also, if you're an older Pokemon Player, watch out for the younger Pokemon Trainers embarking by themselves, especially at nighttime at public parks. And watch out for your surroundings, because you never know when you'll be playing GO and discover a corpse like that one girl in Wyoming.
Remember that Pokemon GO is just a game; don't risk your life for something like that. So have fun, but most of all, be safe.
