I'll have to dig into that more because the Governors executive orders flat out states locals are not allowed to make any rules more or less permissive than the state ones - so the Mayor can't do shit. Either way unless you go down to River Street it's doubtful you'll be in Savannah proper.
Just trying to give the guy a heads-up that Savannah may not be the wide open drunken mess it usually is. Trying to protest the order seems like a good way to ruin his trip but if he feels like coming back to fight it in court in a month or so it's his decision.
