That smoke and fog was the cause of that 80 or so car pileup on I-75 north of you a month or so ago. We have the same thing happening up here in the Panhandle. It's really difficult if you are an early morning or later evening driver. Until the sun burns off the fog...it's fog as thick as pea-soup driving! It was the same way two weeks ago when we were visiting Tampa/Clearwater/Orlando. Best bet is just to wait for it to clear!
