Pools are Closing, River North

Since it is now officially the fall season, I'm sure most area pools are closing for the year.  This pool is located on top of the 28-story EnV residential high-rise - as in the envy of Chicago - located in the River North neighborhood.  Views of the Loop, River North, Chicago River, and Wacker Drive can be seen here.  A friend of mine lives in the building and I was able to photograph a series of images from the rooftop a few weeks back.  You can see the rest of the images in a portfolio on my website.
