What state does My name is Earl take place in?

The state in which the show takes place is never mentioned, but according to the creator, Gregory Thomas Garcia, the show takes place in the fictional county of Camden (not to be confused with the actual Camden Counties in New Jersey, Missouri, Georgia, and North Carolina). Creator Garcia said that the town is named after his son.
The references to Maryland locations (such as Hagerstown, Cumberland, Shady Grove, and Frostburg State University) are due to his familiarity with an area he hails from and that “the show doesn’t technically take place anywhere … we like to think it’s anywhere. We don’t really say exactly where it is.” The pilot episode showed that Earl and Joy drove from Camden County to Las Vegas, Nevada within a single night, suggesting a location in the American Southwest. Also, the frequent appearance of palm trees as Earl and Randy drive around town imply that that Camden County must be in a southern state.
