Traveling north on Avenue 64 in the area one block past the signal light at La Loma and several blocks south of Colorado Blvd. There is a slight uphill grade for a block or so after the La Loma stoplight. Just after I reached the top of the grade and the slight hill grade sloped downward you come into visual contact with a motorcycle officer who instantly pulsed his radar gun. The K band on my detector instantly went off but this would would have been too late for anyone speeding since the location and the uphill grade prevented the radar to be picked up until it was too late. I did not get a ticket since I was going the exact speed limit at that time. One thing to note is that there is a school bus crosssing a block farther down the road so it is not very good idea to speed at all in this area anyway. Some days you may also see the speed radar trailer machines with photo radar used on this street and all the speed limit signs clearly warn that radar is in use this area.
