You see that tree there in the middle?
The one that looks like it's falling down?
Well it is, but in very slow motion. Somewhere along the lines of 2 or 3 degrees per year for - well, to be honest I haven't been keeping track.
In fact I was doing a damn good job of ignoring this slow-motion disaster, right up until The Wife found a tiny little replacement-tree wan-a-be she took a shine to there at the yellow arrow and she made sure I realized that it was in danger of being squished.
I scrounged a few rounds of log left over from taking other trees down and built a little fort around it, but even through my loyal veil of self-denial I could see that wasn't going to cut it, (Oh look! a pun!) and that death-tree was going to have to come down before it inadvertently squashed something important - or maybe even me.
On top of that, once I got to looking I found that there were three other trees, two at the red arrow and one more off to the right, that also looked suspiciously like thugs waiting with raised bats in the shadows of an alley ready to do damage at the first opportunity.
In fact, the closer I looked the worse the situation got!
This is the up-hill side of that leaning tree and obviously things here are no longer on solid footings!
