Although it's not going to start until January, USA Network is already promoting a new series, "American Character along Highway 50," hosted by Tom Brokaw.
We don't have any books on Highway 50, but we do have several on highway travel including The Next EXIT: Your Guide to Gas, Food, Lodging, Medical Services, and Retail Stores at Every Interstate Highway Exit [910 NEX], Roadfood: The Coast-to-Coast Guide to 600 of the Best Barbecue Joints, Lobster Shacks, Ice-Cream Parlors, Highway Diners, and Much, Much More by Jane and Michael Stern [647.9573 STE], and Diners, Drive-Ins, Dives: An All-American Road Trip--With Recipes! by Guy Fieri [647.9573 FIE].
We also have books dealing with highway history such as First Highways of America by John L. Butler [388.1 BUT], and Route 66 Remembered by Michael Karl Witzel [388.1 WIT].
If you have a hankering for a road trip, make sure you take along a few CDs for the trip such as John Mellencamp's Freedom Road [CD ROCK MEL] and Bon Jovi's Lost Highway [CD ROCK BON].
