Chicago winters are terrible. Chicago summers are the best.
We Chicagoans always complain about the winter. People who aren't from here ask, "Why do you stay?" We stay because Chicago is such an amazing city; great people, great food, and a beautiful city. During the summer, especially, Chicago comes alive with our many parks, Lake Michigan, street festivals, and more.
Peggy Notebaert Nature Museum is one of my favorite places in Chicago. Situated between Lincoln Park Zoo and the North Pond, the Nature Walk outside the museum is a short trail where you forget you're in the city. Flowers, bees, wildlife of all kinds, it is a nice relaxing walk and a great spot for some photography.
If you're in Chicago, it isn't the hot tourist spot; sort of a secret that even some Chicagoans haven't seen. I recommend going in the early morning or evening. The light is best, of course, cooler, and fewer people. (Though it is never busy.) When you've been at work all day or running around the city doing the tourism thing and you're just needing something relaxing, visit the Peggy Notebaert Nature Museum.
