The "Happy Days" era is a distant memory. People are more mobile now,  the underclass has grown , illicit drugs are common place, and gangs are vastly more prevalent and better organized. It doesn't matter that Eugene is considered a smallish city, there is no immunity conferred, plus smaller cities tend to lack the resources necessary to effectively combat gangs. Being located on the I-5 corridor doesn't help matters. Expect the problem to grow not lessen.
