Yeah, after having been to some parts of Chicago, I can certainly say that there are areas in there that I'd hardly go to during the day, and some that I literally wandered in the middle of the night with friends and never felt the slightest concern. Things really do vary by neighbourhood.
Although now that I've said that, the very first neighbourhood on that list is one I wandered extensively (by day). Yikes, I didn't know that about it. I always thought the bad stuff was further south and east
Interesting - not one on the west coast. I would've thought some of the LA 'hoods would be no-go...
