There were several koi ponds that made peaceful spots to sit and eat our snacks.
So if you're ever in Chicago and looking for a fun day enjoying nature but the weather is bad, visit the Garfield Park Conservatory. Or don't wait for a dreary day. There's also an outdoor garden that I didn't bother to see. And if you're a city planner in Louisville (or Atlanta, for that matter), please look into setting up a conservatory. We could really use something like this during the winter.
