Portland, Oregon Speed Traps
Interstate 5 is reduced to posted 50 mph just before entering the Terwilliger "Curves", which are gentle and one can safely travel 65 mph through. Laser is hiding behind big yellow sign on overpass above who radios below to array of motorcyle cops who are waiting just prior to Terwilliger Blvd exit. When you are pulled over you are told that the posted speed through the curves is 50 mph.
Eastbound I-84, from Portland to Troutdale.
Where 99e and 99w come together just north of powell, the cops often lurk behind pylons and some of those industrial buildings.
