The less sun the tree gets, the less it grows and the tighter the rings.
That's why the best lumber is cut from the North side of a mountain.

For reasons that I don't entirely understand, pine and fir that
grows slowly (As a second generation of trees in a mature forest)
is much harder than fast-grown pine in a plantation, where the
reverse is true for hardwood.

Doesn't the wheelbarrow section have pre-made replacement
handles, anyway?
