I'm thinking of digging a long, deep hole in one of Brighton's busiest shopping streets.

Well, not thinking so much as fantasising. And as it's a fantasy I might as well employ a team of experienced labourers with yellow jackets enblazened with identical, meaningess initials, and equiped with appropriate heavy machinery.

Pneumatic drills breaking up the tarmac from 0759.30 hours every morning for example. Fork lifts mounting the pavement, Dumspters holding up the traffic. Dysfunctional temporary traffic lights.

In fact, the whole Hole sherbang.

How long would it be before the Council or the Police asked what the Hole was for? Would anyone ever fill it in again? Are there holes like this already, pockmarking towns and villages all over Britland? Dug, maybe by bored, clutzy aliens?
