Years ago before I grew up and knew what I wanted to be I tried law enforcement. There was no need to hide and try to catch speeders you could park out in the open with a clear field of view from both directions and catch speeders. It was just too easy. Only the lazy hid behind things. Best ticket I wrote was at 8 am, 65mph in a school zone. Principal was worried about being late. He was exactly 10 minutes later than he had planned after I wrote him a ticket.
