Freeway Entrance

It was a Wednesday morning, and I was on my way to work. As I was driving, I suddenly realized that I was wearing the same outfit that I had worn on Monday. I tried to turn around and head back towards home, but I couldn't find the freeway entrance that went in the correct direction. I kept driving, and eventually saw the freeway sign at the bottom of a waterfall. I was happy to see the sign, but couldn't figure out how to get to the waterfall...
