Kathy Wilson doesn't pull punches or waste time being nice or sugar-coating her opinions. Perhaps it's because this writer, University of Cincinnati adjunct professor and former CityBeat columnist has no time to be tactful. But far more likely it's because her thoughts need to be heard and there are only so many hours in the day. The one-woman play version of her book of columns, both titled 'Your Negro Tour Guide,' runs at Ensemble Theatre Oct. 17-25.
