If you are planning to be in Dallas for a day trip or longer and you are looking for how best to use your time, let me suggest visiting the Dallas Museum of Art and the Nasher Sculpture Center.  Both amazing institutions are part of the Dallas Arts District, one of the largest in the country.   The Dallas Museum of Art (DMA) is also one of the top ten largest museums in the US having one of the most comprehensive art collections that reflects the entire globe and, surprisingly, admission is free all the time.
