Concentration

Greg has recently ordered a new 'Highline' and was using the time until delivery to practise on the old slackline.
This is the sport of walking along a length of 1" wide tape. On this occasion it was only about a metre off the floor, but the intention is to set one up which is about 70 metre's long and possibly about 200 metre's above the ground.
Hair raising stuff, but very exciting all the same, watch this space !
