So, my wife had a brilliant idea late last night. Look up how many gas stations there are in a given area. And surprisingly, there's gas station deserts almost as bad as food deserts, out towards New Mexico and Arizona. And that brought up the topic of gas cans, in a "fill this up just in case" sense not a "time to walk a hundred miles back to the last gas station" sense. My TV is a modern SUV, not a WW2 Jeep, VW Safari/Thing, or some other "military style" vehicle where I could just bolt a pair of jerry can carriers to the back bumper. And while this next trip will probably be tent camping and we'll probably end up being able to put them on one of those trailer hitch trays, I've still got some questions. Do you folks find you need gas cans very often? Or are there more gas stations than immediately show up on the map? How do you carry them, if you do?
