Going north after you pass the Lincoln/Sepulveda split there is a straight stretch of road that parallels the runway at LAX. At the end of this the road curves to the right. There is often a policeman waiting just before the curve with a radar gun in the early morning (because there is not much traffic so people are going fast). In the afternoon, going south, the police will be waiting at the end of the straight stretch of road just before the junction of Lincoln into Sepulveda. They will be there a few days in a row, then leave for a month or so, then come back. I got a ticket for going 61 in a 55.
