Calm down Steve, I hope you didn't think that I was being serious when I posted the comments about Tellytubby and Gwynant. It was a joke, just a throwaway remark.
Yes, we did want to see the suspended railway track but not one of us would have wanted to go near it let alone on it. You'd have to be a nutter to want to do that and in any case it probably wouldn't support Tellytubby's weight!

Having said all that, the guys in the video were obviously experienced climbers and had taken and assessed all the possible safety requirements before doing what they did.
Similarly the rock climbers we saw in the quarry would have done the same. We don't take risks on our walks either, especially in a quarry like this.
Accidents can happen anywhere, an old friend of mine broke his collar bone when he tripped over and fell down and that was in Mostyn Street when he tripped over a loose paving slab so we are well aware of the risks where ever we go.
