Not quite right. (Although since we have no enforcement of any of the vehicle code, it doesn't matter much.)

Unless it's changed since I last read it, it is illegal to cross the street mid-block in Oregon if both of the nearest intersections are signalized. (I'm not sure what is made of alleys.). While legal to cross mid-block if one of the adjacent intersections isn't signalized, one has no right of way. In most states, not having the right of way isn't that big of a deal since motorists are generally required to take action to avoid a collision. However, Oregon removed that little feature from the vehicle code some years ago. Currently, a motorist with the right of way is permitted to mow down a jay walking pedestrian and needn't even claim to have not seen him/her.

In California, I am aware of a judge who determined that it is always legal to cross mid-block as long as one does not interfere with any traffic. I don't know if he was relying on statute, case law or making new case law. However, it was entertaining to chat with the cop who had issued the citation; the judge ripped him a new one in court for having issued the ticket.
