The red flashes represent lightning bolts. And not just twice, it can strike eight, nine, 10 times a minute in the same area, and here is Nick Middleton, with his laptop and his special lightning software, to show us. Which is a stupid expression, because it does, as clearly demonstrated in Britain's Worst Weather (Saturday, Channel 4). Lightning, they say, never strikes twice.

But what about Martha, a retired doctor, who's at the slot machines in the Hilton? They treat her well, she says, even comped her a memorial service for her husband when he passed away. The rich guys, the mattress moguls, the salesmen, jetting in and blowing their bonus over a weekend, I guess that's OK.
The picture of Vegas that emerges is not a pretty one.
