HALLOWELL — Some local Pokémon Go players have taken umbrage at a sign blocking a wooden staircase next to 210 Water St. The purple sign hanging from a new link of chains says in bright orange capital letters: “PRIVATE PROPERTY – CATCH POKÉMON SOMEWHERE ELSE MORON!!” It’s not the private property that rankles some players; it’s the insult to their intelligence. “It was just the verbiage used,” Pokémon Go player Stephen Turcotte said.
