As the title says, really; next month I'm taking a long roadtrip (think 2500km on tundra) and need stuff to listen to for about 6 days while in the car. Music's fine, but it'll get a bit tedious after a while.
A friend suggested audiobooks, but I reckon the monotonous sound of one person's voice might send me to sleep. Another friend suggested LSE podcasts, which I'm checking out.
So, any other recommendations of podcasts, radio shows etc to download for the trip?
