I own about 3 chain saws, aristo, several brush cutters and two azadas (brilliant Spanish tools). The only chain saw I actually use is a small one on a pole, which is quite user-friendly.
One time, though, I took the largest one back to the shop. The car park was across the road. Cars stopped for me, so I guess others had "trouble with the visual" as well. I smiled graciously.
It's a bit like my eldest son remarked when I stopped all movement on a pavement in Brussels to take a photo of a drain cover "You can't get the mothers".
I still have the NE of the puzzle to do. Please could someone give me a clue for 22? I have worked out 28 but not fitted it in.
Like 4 and 26! Odd that I can't do 43 yet, given my great enthusiasm for family history.
