If I go to Peru it would be for at least two years. Some people like Peru, most don't as a place to live. The younger, single crowd seem to think it's great while the older, married folks are not so impressed. There are a lot of things that are neat, but living in Lima, for us, would be a nightmare. The traffic is horrible and it is a dangerous city... lots of crime and an attitude that one shouldn't really be resisting things like kidnapping, burglary or muggings.
As a tourist destination, it is a great country to visit. Lots of culture, neat places to visit, great food and music and the people are mostly very nice.
My main problem is I don't want to leave the wife alone in the big city while I'm up in the sticks..I can do that here in Chile without much worry. I would be worried to distraction if she was alone in Lima. I never know what's going to happen with this job...one of the "benefits" of doing the kind of work that no one else wants to do.
