The Hall County Board of Commissioners will address several lingering issues when it meets for a work session today. Those lingering issues include what to do with the Tumbling Circle railroad crossing right of way; whether to contract for new credit-card-processing services; and how much money to dole out to rebuild a tennis court in the Village at Deaton Creek subdivision. The board has been trying to work out a deal with the Georgia Department of Transportation, Norfolk Southern Railway and state lawmakers to reopen the Tumbling Circle crossing, which was closed late last year.
