To play Pokémon Go, the wildly popular augmented reality game, players must scour the Earth catching magical creatures that they then use to wage battles with other players in virtual arenas. But during a recent expedition through the little town of Winona, Minnesota, several Pokémon catchers found themselves waging a real-life battle instead. Fed up with hordes of teenagers playing the game in the town’s Veterans Memorial Park, a group of local vets decided to take matters into their own hands and try to force the players off the grounds. The ensuing confrontation was filmed.
