Jones, North Carolina Speed Traps

Rt 70 in posted at 70 mph, going east after Kingston NC.
a speedlimit sign about 3 miles from the limited access portion of the road speed limit 55. No other sign is posted until you are out of Jones county, for 70 but the road is not marked again for 55 when it becomes limited access.
I was tickeded for 70 in a 55 zone and could see the 70, sign about 500′ ahed. total cost of ticket to Jones county $125.00. 70 in the other direction is posted at 55 west, but east is posted at 70. Very confusing, I expect that this is the only money that Jones county gets, so perhaps we should just send them $125.00 per year and get the road posted, with correct signs.
