What relatively small thing would you change?

I'm not talking about a big complex thing, like "crime" or "homelessness" or "the CTA". What's the one little concrete change you would make to improve things in Chicago? Even if it's just for your own experience in the city.

For me, I think the fact that Grant Park has no way to get to the Lake front without crossing 10 lanes of LSD is insane. Especially since both the north and south sides have multiple points going over or under. But for the place where the most visitors to our city come, we're like "visit the lakefront? lol do you like frogger? because if you wait through this 10-minite long crosswalk sign, you can make a dash for it!"
