On a recent sunny Monday, joggers on their morning stroll in Fayetteville's McCurry ParkĀ  might have been surprised to hear thumps, clicks and whirrs coming from the elections trailer next to the parking lot.

Over the course of several days, that trailer 20 miles south of Atlanta was where officials tested close to 300 voting machines to ensure they operated smoothly and accurately. Those machines would go out to 36 precincts across the county for the Nov. 6 midterm election.
