I don't see that it's all that much of a danger, considering we keep two
cars in the garage with twice that much gasoline essentially inside the
house - while this is outside along the fence.

But, my neighbor noticed the four jugs recently and asked about them. I
said I never knew gas to spontaneously explode and he said the sun could
cause it to happen. He also said it's illegal to transport more than a
single five-gallon can in your trunk (is that true?).

Is it all that dangerous to keep 20 gallons of gas in the back yard?
Is it illegal to trasnsport more than 5 gallons (California) in a car?

I would just keep it out of any direct sun, not store it for months as
some volitile components will escape through plastic, degrading the
gas, yes it airtight but not 100% impermiable and be sure you have no
enemies.
