It would have been suicide for 3 white students to travel to the south side of Chicago, so MBI arranged for a police escort. Each week we were met at the metro station by Chicago cops, who drove us to the school. When the class was finished they escorted us back to the metro station.
I suspect that the south side of Chicago - a massive, sprawling, economically-depressed area - is much more dangerous today than it was some 40 years ago. Truly scary.
