Oh geez!
...*sniff*...poor tree. I cannot imagine it's pain... only 20 years old!---
20 years? That's a baby tree! Some are centuries old. And locust trees sprout like weeds and grow like them too! I was born in the early 80s and 8mm film of me outside our house then shows nothing but fields around the house. As far back as I can remember, it's *always* been a lawn and a large wood of locust trees. Weird! Damn it, u don't even need a dozer to crush little locust trees; just use a lawn mower. But they can get to be huge... so you see, trees are doing OK. Very old rare trees, on the other hand...
And your tree is a freak of nature 'cos it's not an evergreen but is ever green anyway. But otherwise the movie itself was ok...
