They are -all- limited unless you find an open gas station. I quickly became aware of that when driving through the mountains on a motorcycle, and then during the Carter gasoline f**kup.
I was used to having 24-hour gas stations but couldn't find any out in the country away from 24-hour jobs, like hospitals.
Since retiring I hardly go through 5 gallons a month, mostly for grocery shopping. I could use a second cheap vehicle with a 10 mile range as long as it has a good cargo capacity.
