The marvellous Becky has been running one of her square challenges again in October, and this time it’s lines. Here I am, joining in for the first time on the very last day with three people walking the line with varying degrees of competence. Tail-end Charlie, that’s me, or as we say up here: the coo’s tail.

The first image was taken on a wet Sunday this summer, through the window of the Kinlochleven Climbing Centre. No, we weren’t climbing  – it was the only place open for lunch and we fell into it gratefully. We didn’t know there was going to be entertainment! The figure on the right, a boy of 16, fell off the aerial adventure course and didn’t have the strength to pull himself up again. In the end, it took two instructors to haul him back to the platform while the whole café watched enthralled. We knew he was roped on and thus always safe, if undignified, so didn’t feel too bad for gawping.

The next image is a busker in Buchanan Street, Glasgow, who managed to play the fiddle and walk the tightrope at the same time. He didn’t fall off, or at least not while I was watching. Most impressive!

Finally, we have John walking the line at an adventure playground in Carrick Forest in Ayrshire. He didn’t fall off either, though I don’t think the Olympic gymnastics team is going to be calling him up anytime soon …

Thanks, Becky, for another great challenge.
