Ignorant newbie question... If I'm supposed to keep gasoline on hand in case we need to get out of dodge, where/how do I store it? : I know you can get those gasoline canisters at auto stores and walmart, but can you just put those in your trunk to take with you when you BO? Is that safe? I've seen special "car safe" containers online, but they're $$$ (at least for me right now) and it would take a while to get them. I really feel a pressing need to keep some extra on hand JIK. What do I need to do?
