Depending on the direction one is driving the speed limit signage is different. Going SW into Golden signs just prior to the intersection at McIntyre are 35. At 1/4 mile before McIntyre the sign goes to 25 for about 200 yds. Right after McIintyre suggested caution speed of 20 mph is indicated due to gentle curves. As the street begins to straighten out there is no signage for a mile or so. I followed a white SUV for about 2 miles that proceeded at 25 mp and then to 20. Finally there appears a 35 mile per hr. sign and the SUV continues at 20 mph. Some moments later the driver pulls over as to let me pass and I then see the sign on his door says Jefferson County Sheriffs office. I accelerate slowly and go about 100 yrds and he flashes his lights , pulls me over to tell me he "had" me going to 38 mph. He also informs me the speed limit sign where he "pulled over" says 25 mph. This is the second time in 10 years this kind of thing has happened to me. It is no doubt a great revenue generator.
