I haven't really travelled much in Canada, only the bit between Niagara and Detroit, but I have driven 10,000's of miles across America and done coast-to-coast twice. Trying to find something worth listening to on the car radio is next to impossible, unless its wall to wall Country music.
American rental cars have the sort of radios that have a scan button, that finds the next station up or down the bands. When you keep pressing this button and keep getting "Hotel California", on different radio stations, you really know the meaning of the word despair !
Sometimes you are lucky and can get National Public Radio, but unless you are in a city, NPR is not very easy to obtain.
So, thank God for the Beeb, because without it, we would have wall to wall pop music ! And those ruddy adverts !
