In early 2010, NASA took this gorgeous shot of Houston, Texas. Captured at night from the International Space Station, this image "depicts the roughly 100 kilometers (approximately 62 miles) east-west extent of the Houston metropolitan area."
In other words, this is one big city, apparently the largest in the United States without formal zoning guidelines. This means Houston's 5 million residents get to enjoy roughly 9,000 square miles of land, which has led to diverse land-use patterns.
I'm not sure what this means for Texas, but it definitely creates an interesting image for us. See it enlarged down below.
