Consider setting your TiVo to record “Alton Brown’s”:http://altonbrown.com/ new show *Feasting On Asphalt* (there’s no good link, sadly).
I watched the first episode last night (I had recorded it on Saturday or whenever it first showed), and it was interesting–the discussion of how mass culture has impacted regional food and small establishments, how changes in the automobile did the same (listen closely for the comment on the ’57 Chevy Bel-Air), so on and so forth.
The most interesting thing, though, was the fact that for all the places he stops, he gives lat-long coordinates. If you have an in-car GPS, you should be able to find any of them. That seems to me to make the whole process something more than your usual “lifestyle program” that natters about places that you’re never really expected to go.
