As of about lunchtime, my self-contained driving range is 876 miles, with a little cheat.
I went to a place with truck pumps, because I figured lines for truck pumps wouldn't be so bad. There were no lines at the pumps, but they only had supreme, non-ethanol, and diesel.
Driving back from my rental house, I didn't see any gas pumps with any activity around them. There may be nothing left where I am.
