How do you carry spare fuel?

Funny I saw the caption for this question and I was going to say in a trash bag as I had just seen this video yesterday on another site and could not believe what I was seeing.
 
I agree with Bill. double bagged...good to go! cost guard should approve that method
 
It's an approved container.... Not.
 
Brilliant. Light weight fuel bladders. So easy to store when empty. Anybody want to buy some used jerry cans??
 
Probably buying extra gas for her generator before the hurricane hits.

People go absolutely crazy here in Florida when a hurricane is threatening.
 
Gotta find a use for those bags as most states are phasing them out....
