We were just at one of these near Beloit. A family member’s band had a small gig. They sell about 100 pizzas on weekends they’ve booked a band. During weekdays, they have limited hours for their store (produce, etc.), and occasionally have breakfast hours. It’s a real farm, but the acreage is small so they also have day jobs.
It didn’t occur to me that it might be a Wisconsin thing and I still suspect these exist everywhere, because the trend seems more about it being easy to buy and install wood-fired pizza ovens, to make and market new Pinterest-ish outdoor event venues, and to work remote jobs that support hobby farming.
