This sound walk is the result of an extraordinary experiment by the author who lived in a houseboat here for ten years.

Making a float out of driftwood and rubbish that collected behind his boat, Toby Butler spent weeks following the float into London guided by the current of the river. Wherever the float collided with the bank, he looked for someone to interview about their life and their relationship with the Thames.

The red spots on the map show where the float hit the bank. Click on a red spot to see what I discovered.
