At the end of the rainbow

I took this photo in Antwerp, Belgium. I saw trams that was running in the street. I don't often see trams in my normal life, so they were fun to watch. A few days ago, I read an article about a cute old woman from Tennessee, the USA who saw the ocean for the first time at the age of 100 years old. Better late than never. Then I thought about things I've never seen and I'd love to see them before I'm gonna kick the bucket. Let's say, the Northern Lights, a shooting star, and say a pot of gold at the end of the rainbow.
