Years ago I got pulled over when radar traps were on tripods.The nice officer told me I was speeding and his radar said 75 mph. I looked at him, while all these tractor trailers were speeding by and asked "does that radar track a Henway" he looks at me and asks "What's a Henway" and I replied "give or take 5 pounds" He then grunted "that'll cost you double". No sense of humor. True story......
