I want to know the answer to the following question:
When did the Uptown district expand?
All the background I'm provided with is that "Centered on Post Oak Boulevard and Westheimer Road, the Uptown District boomed during the 1970s and early 1980s when a collection of mid-rise office buildings, hotels, and retail developments appeared along Interstate 610 west.". Is that enough to answer the question?
Answer: yes
