Carl’s Corner was founded by, and named after, Carl Cornelius, a local truck stop owner and long-time friend of Willie Nelson. Cornelius founded the town for the purpose of legalizing alcohol sales in the otherwise mostly-dry county.
Cornelius’ property adjacent to the truck stop was the site of several Willie Nelson Fourth of July concerts in the early 1980s. Cornelius’ truck stop was also the first to offer BioWillie, the biodiesel fuel marketed by Willie Nelson.
The population was 134 at the 2000 census. wikipedia
