I had turned onto Astrozon from Powers headed west towards Academy. Just about 2 blocks east of Faulkner, a motorcycle cop had a car pulled over and I looked down at my speedometer-40mph. I ‘thought’ the speed limit was 35mph, and when I looked back up a motorcycle cop had got me at the very next block. I was doing 41mph and the speed limit was 30mph. The officer told me that there were 4 officers working a 4 block radius, due to extreme speeding violators in that area. This happened at appx. 10:10 am. He was a very nice officer and showed me the radar gun with out being asked. So ‘Southbourough’ watch out!
