In preparation for my trip to Spain in November, I have begun learning Spanish. I am using the podcast "Coffee Break Spanish" from Radio Lingua and it is really great!
I listen on my way to work or on my lunch hour (where I feel less self-conscious repeating "Soy de Los Estados Unidos", etc.).
I have already impressed a co-worker by saying "Hasta Manana" at the end of the workday.

Adios y Hasta Pronto!
