I always like to look at the map for weather report of the us. I can just stare at a city and its temperature for a long time.

In 2001, I looked at the weather report in north western area. I changed my way of measuring temperature - from Celsius to Fahrenheit.

In 2002, I was used to the Fahrenheit system. I knew that when it is 60F, it is cool; when it is 70F, it is kind of warm.

In 2004, the temperature changed dramatically. It has primarily 70-80F.

Now, I am at a city where I had looked at a weather report map for a long time. It feels weird, as I am actually here !
It is in its 70sF now, but I know it will get much colder.
