This entire I-75 corridor is the domain of both the local sheriffs and the Georgia Highway Patrol. This has to be the longest speed trap known to man. Speed, even a little, at your own risk. It’s nothing personal. The Georgia LEO’s know I-75 is a major north-south Interstate and a ticket-writing haven. The average victim is from out-of-state & won’t show up to contest the ticket so they take advantage of the opportunity. There is very little that can be done except set the cruise at the speed limit.
