Shaking his head at the diverse variety of Mexican and Latin American food options being made available to him, area shopper Steve Unger told reporters Friday that the Hispanic food aisle at his local grocery store pretty much told him all he needed to know about where America is heading. Black beans, tortillas, hot peppersboy, thats the whole story right here, said the visibly dismayed Unger, 49, who recalled a time when Latin American items only constituted about a third of Aisle 14s offerings at the Kroger on Miami Avenue and Americas dominant position in the world was completely unquestioned. Look at these names: Goya, Tapatioits the whole damn aisle! How many types of salsa do you need, for crying out loud? At press time, Ungers ire had only grown more intense upon passing by a small refrigerated hummus display.
