It’s about 500 miles (less, but I’m adding in stops and traffic etc) from my house to where we are going (Middle of SC to Orlando FL)

I’m a tad worried about the gas situation. Leaving tomorrow mid afternoon and will be down there through Sunday and my car will be parked the whole time. I think the further this progresses the better it’ll get but short term driving down there, would y’all suggest I take a gas can (or two) as a safety net?

The vehicle we are taking can’t make the full trip (400 miles and it’s on fumes). I could take say my oldest can or two just to top off with down there and give us a buffer for the return trip or driving around locally if necessary and I don’t mind throwing the cans out once they’re empty to prevent enticing theft /sitting in the sun/etc if necessary

So, should I take a gas can or two or just count on there being gas somewhere? Grade and cost is irrelevant as long as it’s available.

EDIT
Rescheduling is not a possibility
