The Notes in Spanish podcast came to life to help me raise money for a charity motorbike trip - 2000 km across rural Southern India in two weeks on a Royal Enfield! You can listen to the podcast, read all about it, and see the photos here.
Our idea was to do one podcast every day for a month before the trip, a sort of sponsored podcast marathon. After I came back from the trip, we decided that the Spanish podcast was worth continuing. At the moment we are not podcasting for charity, though we hope to do things for good causes from time to time on this site.
