Rune – i was reading this and thought of you!
“Lyttle—who once quipped that “tunneling is something that should be talked about without panicking”—became internationally known for the expansive network of tunnels he dug under his East London house. The tunnels eventually became so numerous that the sidewalk in front of his house collapsed, neighbors began to joke that Lyttle might soon “come tunnelling up through the kitchen floor,” and, as a surveyor ominously relayed to an English court, “there is movement in the ground.””
and here is a nice poster showing tunnel digging as a hobby! We should start digging – by the end of next year I will be able to walk home… to London!
