Phallic Precipitation

At Chicago's Millenium Park they have a bunch of large aerial photos of the Chicago area displayed all over the place. I was looking around last time I was there and saw this one of a skate park on the south side.




It showed the park in the summer and in the winter. Looks innocent enough, but if you look closer you can see something written in the snow shown here.

If I'm not mistaken that looks very similar to a penis. A massive snow penis complete with a pair of balls.
