It seems that street art is on the rise. You could find murals, graffiti and sculptures at more and more places. Even the very commercial Dallas, Texas, is open for this manifestation of culture.
The district Deep Ellum (wikipedia), east of Downtown Dallas, reminds me of Williamsburg, a neighborhood in the New York City borough of Brooklyn. There are a lot of old and abandoned factory buildings and storage depots which are now used by artists and are home to restaurants, bars and pubs. As usual lower rents and relaxed regulations are attracting alternative entrepreneurs.
The result is a somewhat flamboyant and bohemian environment in a very busy metropolis.
