I'm getting trypophobia

Wow, 21 Zacians, that's amazing! Where did everyone go? It's a perfect day for raids :D

There are maybe 1-2 people, if that. It depends on the region, but where I am in Cheongju, there are about one or two people participating in raids.

These days, except for a few famous Pokémon GO hotspots where people gather, it's rare to see consecutive raids during Raid Hour.

Except for those times when people team up occasionally.

There are KakaoTalk group chats for each neighborhood. If you find and join one, it'll show you where people gather. There are designated spots like Gangnam Station in Seoul and Rodeo Street in Incheon.
