A bus service may someday be available for elderly residents of Covington, but not now, not yet. Monday night, the city council voted 4-2 to ask staff members to explore the idea for next year’s budget, but rejected applying for a state grant to buy busses due Aug. 4 because of its timing. At its July 7 meeting, the council asked financial coordinator Randy Conner to look into the grant and what it might ultimately cost the city to pursue it.
