I had the slackline for my sixtieth birthday, blahblah years ago. It's slung very low and needs adjusting, but the point of it is not to do a high wire act: I want to be able to walk from one end to the other without falling off. I used to be able to walk half way, but the line's been in the shed for a couple of years, and I'm out of practice.
So this is me, learning again to balance on one leg. Next week, I'll be trying the walking thing.
Meanwhile, in Colorado, 5 year old Lux is making up tricks of her own. Check this one out.
Yes, I'm a proud grandmother! Sue me!
