My family is considering moving to Vancouver... does anybody here know the city fairly well?

We're concerned primarily about locations WITHIN the city, which are good or bad for crime, air quality, etc...

It seems to be fairly good in terms of tech jobs, plus I want to try out for the Vancouver TheatreSports league (the place where Colin Mochrie and Ryan Stiles of "Whose Line Is It, Anyways?" fame got their start...)
