Yeah, the 'burbs, lotta money goes into paying cops to focus on stupid ticky-tack traffic shit. But, there's something to be said for that. With two kids, I'd rather have that, be able to keep my door unlocked, all that jazz..... than the other shit that goes down. West Linn's crime rate is the lowest in the state, and the one reported violent crime last year was a domestic case. Slice it how you want, but with two kids, I'd prefer uber-vanilla 'burbs to living closer in or Greshman (plus, the schools and parks are top-level).
That being said, I travel enough to see that the PDX-metro is uber-safe compared to every other major metro area I've been too. Aside from the gated communities in bigger cities, walking through most any streets in the Portland-metro area at night aren't any more dangerous than anywhere else I've been.
