You know where you should go? The Lincoln Park Conservatory.
A lot of the time, I'll pretend to like places because I feel like I should. The Field Museum, for instance, is a really interesting and informative place. But, honestly, it hasn't changed since I first visited it twenty years ago and now I'm bored as shit after about ten minutes of wandering around staring at old stuff. It's one of those places where if you've seen it once, you never need, or want, to see it again.
Honestly, where else can you see this thing without going to a rainforest?
