I legit sat in line for 25 minutes to get gas by DFW this morning! The fuel shortage in DFW due to Hurricane Harvey is real, and some places are running out completely! The owner of my favorite gas station/taco shop, Fuel City said it's the worst since 1980!
Quick Trip was nice enough to list where you can still get gas in DFW as of this afternoon. The list is here
