While walking back to my hotel, I noticed a side street was was all lit up by lights on the ground and from above. I walked down to investigate and realized that all the cars parked along the street were about as old as I am. It turns out I had gone back in time to 1973. Well, not really. What was going on was they were filming a new TV show called Life on Mars in which the main character somehow gets transported back in time to 1973. Even so, this was close enough to time travel for my imagination.
Whole set here.
