Well they do it in Yosemite and now they do it on Great Gable. Circus stunt or the act of having an unbelievable amount of fun walking and doing tricks on a piece of webbing pulled tight between two points, also used as a form of meditation, physical and mental training. You've no doubt seen the likes of bad boy Dean Potter doing it in one of those high-energy American climbing videos or in a Patagonia advert. Will it now take off in the UK?

But is it a slackline or a tight rope walk? Well you can join the discussion down the forums on this thread and even watch the video at you tube and if your interest is really piqued you can read all about it at the Slackline brothers website which includes a history of slacklining.

What would WP Haskett-Smith say?
