I want to know the answer to the following question:
What is the southern edge of Tucson's downtown?
All the background I'm provided with is that "Downtown is generally regarded as the area bordered by 17th Street to the south, I-10 to the west, and 6th Street to the north, and Toole Avenue and the Union Pacific (formerly Southern Pacific) railroad tracks, site of the historic train depot and "Locomotive #1673", built in 1900.". Is that enough to answer the question?
Answer: yes
