Parking. Like everything else in Portland, it's weird.
Parking in the wrong direction.
A one block walk around my Alberta Arts neighborhood revealed 4 wrong-way parkers. You'd never see that downtown, but in Portland, we take it for granted that our City Parking Enforcement doesn't patrol residential neighborhoods, like mine...unless it gets a complaint. So long as you've been neighborly, you should be in the good to park in whatever direction you want.
But it's weird, right??
