But other people (granted, not with your charm) say that because of my previous post on looking up, it should be because of no sky, not no trees. No cigar for you :-)

And it's still possible that I could pull a correct answer out of a hat as being no grass! Wouldn't that set the hounds a'braying :-)

The no grass is quite plausible and when it comes to @onceuponatime and his multi view of life, I don't doubt it could a real answer here.

However, we all know that the excavator itself is anti-grass -- it destroys grass too. So even if there is grass in the excavator picture it shows destruction capability with a dying heritage.

It's all quite fitting the more you look at all of it. :)

Yeah but "You decide:" so I decided it's the trees and now it's settled!
