Heading south on US 321 about a mile before the I-85 on ramp, it looked like a wasp nest when I travelled through there on my way back to Atlanta around 10 PM, but saw it too late. Got a $170 ticket for 70 in a 55. Explained to the officer that I knew I was doing 70, but sincerely thought the speed limit was still 65, to no avail – there were two other cars pulled over by the time I left. The speed limit drops from 65 down to 45, well before you hit any area congestion, and apparently pretty rapidly. I never saw any speed signs, but it was at night – thought I was going with the flow of traffic. I received letters from three different attorneys soliciting to "defend" my case. I guess an entire economy is formed around this town’s speed traps.
