I hope the Tour de Georgia does continue. The word in the cycling media years back was that the Tour de California would kill the Georgia tour. Supposedly, there's only room for one international tour in the US.
Possibly, that's what happened to the sponsors. They went to California. The Georgia mountain terrain is a lot more like the French mountains than California's. At one time, they were actually part of the Alps.
With out fans, you don't get sponsors I would think.
