“Raidless gym” from a few months back did not spawn Articuno during the 3 hour event.

Did anyone click on the gym during the first hour? I heard that some gyms have later raids than other gyms.

Another amazingly cool story, dude.

Thank you all that are posting information from the future. Do gyms that are hosting an EX raid next week have an Articuno appear? I'm guessing it doesn't, but if it did then I could get all 5 at one very busy park.

Two gyms in Tampines Central Park did not get Articuno.

Heard that gyms at industrial areas, churches/mosques/temples, etc. can also have raids permanently disabled if the management complains to Niantic.
