Niantic is committed to giving the fan event another go this summer, expanding the outdoor celebration to a full weekend this July. >Pokémon Go Fest 2018 is subtitled “A Walk in the Park in Chicago,” which speaks directly to what Niantic will have players doing this summer. On July 14 and 15, visitors to Chicago’s Lincoln Park will follow a nearly 2-mile trail to discover rare Pokémon, check out physical guideposts and participate in “exclusive activities,” which Niantic remains vague about.
