The trap happens between Colorado St. and Hungtington Blvd. When Colorado St. forks, the right hand side turns into Colorado Place. Colorado Place is immediately adjacent to the infamous Santa Anita Race Track in Arcadia, CA. There are small pull off points all along this stretch of Colorado Place that are intended for in/out flow of traffic for the race track parking. The officer generally sits next to one of these blocked entrance/exit locations and points the radar north towards Colorado St. Colorado place is a nice speed trap since the speed limit is reduced down from 45 MPH to 40 MPH after a blind turn and a downhill. Suffice to say it’s hard to see the speed limit sign if you’re not paying attention. The Colorado St. speed limit is 45 MPH but the traffic flow is generally 55 MPH. It’s really easy to speed on this stretch of road, and many cars do.
