In the past couple of months i have had to completely drain out gas tanks of a few classic cars that customers have been having issues with as well as rebuild carburetors and flush out the rest of the fuel system. Don't know how the quality of the gasoline is in the rest of the country but here in AZ it is garbage. I would recommend if your going to let your car sit for any length of time to drain the tank and run the carb out of fuel.
