Back in the day, when all I had was a stock Honda AM/FM radio with cassette but the tape player was broken I'd go to NPR.com and get the frequencies for all the NPR stations along my route. That way I always had NPR while I drove.
LadyFirelyght it doesn't seem like that's a problem for you, though. I thought it might help someone else, however.
Otherwise, get a portable DVD player for in the car and you can watch movies or something too.
I don't know about this. I mean, Lemmy knows when I was a kid I would have liked nothing more than a portable DVD player and an entire season of
The A-Team but we didn't have that stuff back in the 80s. I think watching television on a road trip is the worst thing you can do. Play
roadkill bingo, or "I Spy," or look at the landscapes, or check out the other cars. Go to all the weird tourist traps along the way. "Deepest Cavern in Idaho," "Largest Ceramic Lawn Gnome in the West," "The Walt Whitman Once Stopped To Use The Bathroom Here Motel," etc.
If you're taking a 2000 mile road trip, you'd better show up in Seattle with some cheesy snow globes from the stuff you saw along the way.
