I grew up in Southern California in the 1960s. Guess what? People were friendly, jobs were plentiful, real estate was affordable, schools were great, the freeways weren't loaded with angry a******s. Then a bunch of people moved in from other places and it changed. People are going to keep moving to places where they think they can make a better life. Should every person that wasn't born here stay out of Portland and the rest of Oregon so that you can keep your pristine childhood memories? Should I have expected that to happen in Southern California? I recommend you cling to your polaroids because everything changes always. Time is not going to freeze for you or anyone else. People are not going to stop moving to Oregon because it makes you unhappy. You don't own it. Try to be grateful for what you have.
