In reply to neilwiltshire:
Hi Neil - fantastic find!
Before today I didn't think the American's had such a great sense of humour - my mistake, cos these boys in Colorado have really gone to town on this practical joke... made me laugh out-loud even before I started watching the video's!
I really like the idea of attaching special adapters to my screws with a tiny allen screw and key - inspired.
But the thought of power drilled chunks of ice being blown out and cascading down the crag stopped me laughing!
I hope you've settled OK in Leeds.
Cheers,
Paul
