quality and cost-effective cultural assets that promote a distinctive urban life. Other cities, such as Macon, Georgia, experimented with renovating shotgun houses for low-income residents and, though there was indecision whether it would be cheaper to tear them down and build new housing, some were rebuilt. There are many large neighborhoods in older American cities of the south which still contain a high concentration of shotgun houses today. Examples include Third Ward in Houston; Bywater in New Orleans; The Hill in St. Louis; Portland, Butchertown and Germantown in Louisville; Cabbagetown in Atlanta and Village West of Coconut Grove in Miami where the last remaining 25 shotgun homes have been designated as historic structures. Their role in the history of the south has become recognized; for example, in October 2001 Rice University sponsored an exhibition called "Shotguns 2001". This three-day event featured lectures on and artistic paintings of the houses, as well as presentations and panel discussions in a neighborhood of restored shotguns. In some shotgun-dominated neighborhoods, gentrification has led to property values becoming quite high. Sometimes, a new owner will buy both homes of a double-barreled shotgun structure and combine them, to form a relatively large single house. Shotguns are also often combined to renovate them into offices or storage spaces. Limited revival Elements of the shotgun style have recently been seen in a number of the compact, low-occupancy structures employed in the Solar Decathlon contests held periodically in Washington, DC. While some are erected from panels brought to the site, many such structures consist of enclosed single or multiple units designed specifically for road transports, with multiple modules connected on site, and compact linear structures often employ multiple-use "zones" rather than specifically private areas, while retaining a linear progression of spaces. In 2011, Louisville's daily newspaper The Courier-Journal reported that a local nonprofit agency devoted to building and renovating affordable housing was building new shotgun houses in a development in southwest Louisville. Popular and Southern culture The shotgun house plays a large role in the folklore and culture of the south. Superstition holds that ghosts and spirits are attracted to shotgun houses because they may pass straight through them, and that some houses were built with doors intentionally misaligned to deter these spirits. They also often serve as a convenient symbol of life in the south. Elvis Presley was born in a shotgun house, Aaron Neville of The Neville
