Dave keeps it local

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Dave starts out by cutting his shirt in two, and placing the two halves in different locations. He initially puts one of his socks up on the scaffolding, at the edge of the garden, but then appears to realise that he can leave the property. He is seen walking up the road and getting on a bus. He also stops a cyclist and asks if they’ll take one of his socks with them, to the end of their journey. The cyclist obliges, and says they’re going as far as East Cheam. Dave then plans to get on another bus but, as there isn’t one due, he instead continues to run along the road as his time runs out. In the studio, Greg points out that Dave had effectively used “clothes mules” to distribute his clothing for him, and he compliments him for getting on a bus, where he had left one of his socks. However, Greg questions why Dave had decided to cut his shirt in two, and Dave explains that by doing so, he could spread it further and wider, as he’d have “five nodes” to play with, instead of four. Greg argues that a split shirt is no longer a shirt, but then Alex points out that Dave had used the word ‘nodes’, and that seems to win Greg back around. The area covered by Dave’s clothing is revealed to be 0.3 square miles, which earns him third place.
