UW-La Crosse public administration professor John Kovari made his WIZM debut, and helped try to explain the recent tax revaluation in the city of La Crosse — and elsewhere — and what that means for people's property tax bill. In the midst of that discussion, Kovari uses a Big Mac analogy. And, in no relation to that analogy, Kovari also talks a bit about taxing our vices, including Wisconsin legalizing recreational marijuana.
