County ambulances likely get fueled from county owned pumps that supply only to county vehicles (police, ambulance, fire, bus and other), so probably no issues.
So, prices went up a little, we will see if they come back down to last weeks prices or if they stay the same. Ga prices were frozen by the governor, yet they still went up from $0 to 30 cents higher overnight.
Most stations are out of 87 octane so everyone is having to buy the higher priced fuels. If I owned a station I would only order in 93 octane, but surely nobody is doing this...
