Last week at some point I took the subway to the Union Square stop. When I left the station it smelled like a combination of B.O. and garbage. It must be summer.

Over the weekend I went to Central Park to play frisbee with a few friends. There were probably a thousand people in Sheep Meadow. Most of them were half naked. It must be summer.

Every single corner in my neighborhood has been ripped apart and repaved. The jackhammers are really loud. It must be summer.

I'm sure that more of these will come to me as we get deeper into the summer months. Add your own in the comments.
