Police and social workers have noticed that it's somewhat common with youths integrated into gangs often never leave the "safety" of their neighborhoods. Their encounters with the justice system may be their only experience with leaving their neighborhoods.
I knew a guy, 30 years ago, who grew up in Toronto, moved to Ottawa, and got there by taking the bus.
He had literally never been outside, unless in the downtown core of a large city. Never.
And this is in Canada! Wtf!
