My son and his wife have a lovely place in River North. I seriously don’t even want to go visit them. At all.
River North is still a nice area, even with this recent shooting.
Like the other poster said, Chicago is split very sharply between “safe” and “not safe” areas. River North is clearly very safe. It may be even below the national average for violent crime.
Personally, I hate the Chicago area much more for the fact that most people are more than just unfriendly. Whenever I leave to go to Wisconsin or Indiana or some other state people are always so nice to me and I am constantly shocked that humanity is not so evil.
