Dallas has one of the largest art districts that I know of in the U.S. That being said, there’s so many pockets of galleries in the city. A must for photographers is the PDNB Gallery. Known for showcasing work of established photographers, this small space is a great place for rainy days and Mondays. You have to ring the doorbell in order to get in but after that you’re on your own checking out tons of work. The gallery rotates work every six months or so be sure to get on the mailing list for more details. And the gallery is free!
