There’s one thing worse than the high price of gasoline. That’s not being able to get gasoline at all. Most people in the US don’t think about that. It could happen and it has happened.
We’ve come dangerously close to running out of gas in sizable parts of the country due to hurricanes. When pipelines are damaged the clock starts running. Local supplies don’t last that long. In fact, authorities have downplayed the damage to prevent panic buying. It worked too. If everyone decided to fill up at the same time the system couldn’t handle it -and that’s during normal times. Add in an actual supply issue and gas could easily run out.
There are things that can affect local supplies. Areas have run out of gas for various reasons. Locally we once ran out of gas due to a blizzard. Just a few days delay and gas stations were closing right and left.
During the Arab Oil Embargo supplies were spotty. It wasn’t impossible to get gas, but it wasn’t always easy. There were times when you could only gas up every other day depending on your license plate number. On a long trip it took some planning as gas stations did not stay open 24 hours. I remember being parked in front of a gas station early in the morning waiting for it to open.
I don’t store a lot of gas at my house. The stuff is dangerous. I have a storage place that can be locked located outside. Even with stabilizer it doesn’t last too long. You have to keep rotating the stock. Rather than try and store a huge volume of gas it might serve you better to figure out how to get by without it.
