It's not illegal to run away in Oregon. Your parents will have to contact the police and report you as a runaway, but unless you're in immediate danger not being at home (or pregnant, on medication, suicidal, etc.) nothing will happen. They have to know that you ran away though, so there would have to be a note or something like that explaining that you've left instead of getting kidnapped. I think there might be something about having to be at least 13 to legally run away, because any younger would make it hard to survive and would be dangerous, but I'm not sure. If you're in your teens and they know you've run away and not been stolen, nothing will happen to you.
