Sometimes when I'm feeling especially Texas-y, I listen to KSHN 99.9 out of Liberty County. Though you would expect country music on a rural Texas radio station, they play a wide variety of music including a lot of soft classic rock (Boston, Kansas, Steely Dan, etc.).
The part Hank Hill would like are the very local news reports (including local obituaries, farm equipment thievery, church news...), the fact that all of the announcers have a pleasant East Texas accent, extensive coverage of the local high school football games and the farm reports.
I think Hank and Peggy would love it.
(Right now, they constantly promote the Trinity Valley Exposition Fair. I'm pretty sure Hank and Peggy would be attending.)
