The Trigger

[One-eyed Wonder]

I now have a tried and tested preferred crossing of Kinder from Kinder Gates to Grindslow Knoll that only involves one Xmas tree.

Yes, that's one useful tree! It did occur to me it had been planted specifically for this purpose-is that the case?

have you noticed how all the black pegs keep moving and the white grit sticks??

No but I'll not rely on them now!
