“What’s a PodGuide?.
A PodGuide is a very simple thing. It’s the combination of a map (PDF) of a certain place and a series of audio tracks (mp3) which you can download for your iPod. Think of an audio tour in a museum, but not limited to just that. You could have a PodGuide about the 10 coolest pubs in London for example, or a PodGuide which shows you the most known historic buildings in Bruges.”

I would love to see this take off for other cities. Even if you don’t have an iPod, you could burn a CD of the audio files and listen to it while driving to your destination. Instead of listening to the never ending chorus of “Are we there yet?”, you can learn about the places you are visiting.
