In just a few more hours, the first-ever Pokémon GO Fest will officially be underway at Grant Park in Chicago, Illinois. Although the event doesn’t start until 10 a.m. CDT today, July 22, it has already been set up with gates, steel barriers and event tents. Thousands of attendees will be able to encounter a Legendary Pokémon in an Raid Battle. If they defeat it, the Pokémon will appear at Gyms across the globe beginning July 23.
