Does anyone have an explanation for the window display in the building at Pennsylvania and Georgia streets across from Conseco Fieldhouse? The banners spell out "A new city is coming!" and include images of police officers and a skyline scene. Officials in the city's planning department say they're not sure what's going on, and officials with building owner CSX did not return phone messages. Is the display teasing a new building tenant, or is it public art? Maybe a guerrilla marketing strategy? Stay tuned. We'll figure this out.
