This post is inspired by http://www.nicaliving.com/node/19748 which is a photo of a house in Jinotega and the followup comments. A bad neighborhood in Jinotega?
While I am no Jinotega expert, I have spent some time there. I saw poor and not so poor neighborhoods. Maybe I missed it/didn't recognize it but I never saw what I would call a bad neighborhood. That is, one that felt dangerous.
When I first moved to Estelí I lived in El Rosario, I very poor neighborhood. But, poor in Estelí and dangerous are two very different things. I have an aunt who lives in a dangerous (because of the drug industry) barrio in Estelí which also happens to be poor.
Having grown up in Los Angeles, I am very aware of dangerous neighborhoods and they always seemed to be poor. But I don't think poor necessarily means dangerous, particularly in Nicaragua.
