When trying to lay out the reasons why someone should visit Houston, it is not uncommon to come face to face with the reasons not to come here. The heat, the sprawl, the traffic — we've heard it all before. This is why a trip to the Museum District should be a requirement for all tourists. Not only does it boast some of the finest works of art you'll find anywhere, but it's situated on lush, oak-tree-lined streets that are the antithesis of what most people think of when they hear the word "Houston." And if the heat is a problem, all the stops are air-conditioned.
