Officials in Hall County, the city of Gainesville and the Greater Hall Chamber of Commerce agree the Lake Lanier Olympic venue at Clarks Bridge Park is a gem that could bring in some economic impact. But the infrastructure has needed major work for years, raising the same questions discussed before — who’s going to pay for what and how is it going to be operated. Richard Mecum, Hall County Board of Commissioners chairman, said recently he hopes to have a good idea of how to tackle the problems facing the Lake Lanier Olympic venue in the next four to six weeks.
