Hi there, My wife and I (https://www.couchsurfing.com/people/stephanie_flrs) are road tripping around the US, and just arrived to Portland after driving from AR to CA and CA to OR. We'll most likely end up sleeping in our car tonight since we haven't found a place to stay. Any idea where we can do that in or around the city without getting into trouble? My phone number is 479-800-4113, thanks a lot in advance! Rob
