Bigfoot is big news again in the United States. Not since the late 1960s, when grainy footage first emerged of a giant, ape-like creature walking upright through the woods, has there been so much interest in proving its existence.

The Kentucky Bigfoot Research Organization is a group of friends who spend their spare time investigating sightings and attempting to communicate with the elusive beasts some call the Sasquatch. They demonstrated their methods for the BBC.
