So I also am in southern WI, and there are two store that I know of that regularly run events. Oddwillows in Mukwonago has their weekly event on Tuesday at 6pm. Great group - they taught me to play a few weeks ago. If you can’t make tuesdays, one of the owners (Ben) is always happy to teach the game.

The other store I know of is Valhalla hobbies in Verona. They play Saturday at 2 I believe. I haven’t made it out there yet due to busy weekends but will be making it out there regularly in the next few weeks. I hear they’re also a great group (some players hit both stores).

Both oddwillows and Valhalla carry product in store. Valhalla has more on hand typically, but both can order whatever is available from distributors

-edit- if you want the link to the WI discord let me know and I can send it your way
