I have done a fair amount of traveling this year and purchased gasoline in many mid-west and east coast states that I have traveled through. I never really noticed any foul odor from burned gasoline, but the smell from the raw fuel coming out of the pump is terrible. At first I though it was because they don't have fume collectors on the pumps, but it is the actual fuel. I pumped some gas in a 5 gallon can for a generator and it just oozed fumes that are destined to give you a headache in no time. It smells nothing like the fuel that comes out of the CA,AZ and NV pumps.
