No more dangerous than filling up your lawnmower gas tank!
Here's an idea, taken from your local airport, where a standard preflight operation is draining a sample of fuel from each tank and checking it for water (which always settles to the bottom of the tanks). Failure to drain off the water (usually from condensation in the tanks) often results in a crash. So if you need to easily remove the ethanol for your A, mower, saw, etc., find a tank from a wrecked light plane and mount it in a stand in the same position as it was in the plane so that the sump drain is the lowest point. Add the appropiat amount of water to a five gallon gas can and fill it whenever you fill your daily driver. Shake and add to the plane tank. When it's full, wait a few days and drain off the ethanol/water sludge. Presto! Non-ethanol gas! Leave the plane tank outside. After all, airplanes often sit outside.
