Traveling With a Teenager

I know the distance between Dallas and Houston isn't all that far. But with a teenager in the car, it seems to go on forever. We made an agreement. I could listen to WBAP until I lost the signal, and then we'd listen to her music. Luckily, the station lasted till Hunstville, which is about 80 miles from Houston. Just how much Green Day is an ol' broad suppose to deal with??
