For everyone playing Pokemon Go…

Make an account on Ingress so you can access the Ingress Intel Map. Niantic used Ingress portals to create the Pokemon Go map, literally every single gym or Pokestop is a portal in Ingress, the Intel Map will help you find good areas to gather items or battle gyms in for Pokemon Go. Look for areas with densely populated portals. Downtown cities, larger shopping centers, tourist locations, and college campuses tend to be GREAT areas.

Also invest in an external power source lol
(I have TWO I had bought for Ingress because of events)
