Judging by the recent small shtf events even approaching a gas station in a full scale SHTF will be a death sentence.
911 was an interesting warning about how quickly gas can disappear and how dangerous it can be as it runs out.
On the afternoon of 911 I was at a gas station with a couple of friends. When we finally got to the pump we had guys with cans getting aggressive about wanting to pay us to fill their cans before people in line behind us.
That instant shortage was just a few hours into a purely psychological crisis where we didn’t even lose electricity.
One of the reasons I've got sufficient fuel storage for better than 1250 miles for one of my pickups. But if that load of fuel goes up, that too can be a death sentence, and it can be a temptation for others who are aware of it.
You pays your money and makes your choice. But it's an option, to be considered, and used or discarded as circumstances dictate.
I don't figure on approaching gas stations much. Last time I made the run from Indiana to Wyoming, I ran it as a shakedown exercise, with no gas station pit stops, though refueling in remote campsites was necessary, three times.
Go in a convoy, burn more fuel- but you've got more hands for the work, and more eyes/ears/hands for site security. An option, as circumstances dictate....
