>> As trees grew in the cleared lands near roadsides, kudzu rose with them. It appeared not to stop because there were no grazers to eat it back. But, in fact, it rarely penetrates deeply into a forest; it climbs well only in sunny areas on the forest edge and suffers in shade.

Last time this article came up, I realized how much of my impression of kudzu was visibility bias.

You see a ton of it from roads.

You see very little of it inside forests, where there are not roads.
