Police vehicles sit on El Camino waiting for the morning traffic heading west to I-80. Sometimes there will be several police vehicles and usually at least 1 motorcycle. They are waiting for people to "roll" through the stop signs on Dickson Hill Road. Since there are several stop signs on Dickson Hill, by the time you get to this last stop sign before N. Texas street people tend to "roll" through. The police sit on El Camino, but because of the angle of the road, you cannot see them until you have already gone through the stop sign.
