Well, as far as I can tell, it's described as a rural place where people are not really smart and generally full of prejudices. And where girls are rather slutty - apart from the main female character, who is, of course, a virgin. I guess those are more or less the general stereotypes about southern states, right? The only other series I can think of which had a similar setting (apart from the slutty girls, but there were still waitresses in tiny hot pants) was "Dukes of Hazzard", and it was set in Georgia.
