So you're thinking about learning another language? Want to brush up on some skills before you fly over the pond, down south, or over yonder?
If you have iTunes, you should check out the free language podcasts. (Note the word FREE!) I am trying to brush up on my Italian, so i DL'd a bunch the other night. I mean, you're gonna listen to your iPod on the flight anyway, right? :)
Save some room in your luggage, and try not to bring so many "How to speak __ fast" books and toss some podcasts on.
You could even listen to the podcasts in your car while you're driving to work (if you have to commute) or at the gym.
