In reply to Mark Lydon: Good for them. It's mobile phones isn't it? Now if someone doesn't get down in the evening and doesn't phone in, everyone presumes the worse. I think it's an Andy Nisbet story about running off Ben Nevis one morning having spent the night out in an emergency snow shelter, to get down to the police station by 9 am to report in safe before the MRT got called out. Getting there a bit late, very apologetic, and the desk sergent saying: "never mind lads, we had 16 reported missing last night, but you two aren't on the list". Their mate who had known what they were up to had gone to a party and forgotten he was meant to check they were down safe!
