Citgo used to have a handful of gas stations in my town some years back. After the word got out they were using Venezuelan oil, enough people boycotted the stations that they all closed down within a year. Haven’t seen on in the area since.
You live in a great area with a lot of good patriots! Unfortunately, here in the People's Socialist Republik of Connecticut, Citgo stations are thriving... people are always at the pumps, getting their "cheap" gas (selling their souls to the Devil, IMO).
My husband and I have been boycotting Citgo for many years, even though their stations are all around us...
I know of several that closed in my area. The ones that remain open are in small towns as the only station.
