Greenfire Games in Oak Lawn, IL is having 2 back-to-back Armada nights on April 12th and 13th.
It looks to start at 6pm both nights and continue until folks are done playing. Maybe good practice before the next big event?

Are they continuing next week?

Yes, from what the owners of the store are saying every Wednesday and Thursday will be Armada nights.
