Rush Hour Commute

So, the mystery that we are trying to solve is: when do people in this city work? It appears that rush hour lasts from approximately 9 o’clock in the morning until 7 at night. We got on the subte today to head to El Centro (downtown) at about 11:30 and it was completely packed. Not only was it really crowded, but the cars don’t have A.C., so it was about 100 degrees. Yet, we looked around and we were the only ones sweating. Why is that? Anyway, we decided to hop off a couple of stops before we got there so we could avoid passing out, thinking that we would get away from the crowd. Well, we got to street level and it looked like the Loop at 5:00 in the afternoon…people and cars everywhere.
