Is this sentence wrong?

[jasonlulu_2000]

There is space for our three boys to play outside, to shoot arrows, collect tree seeds, build earth houses and climb trees.
Our kids have learned the names of the trees, and with the names have come familiarity and appreciation. As they tell all who show even a passing interest, maple makes the best fighting sticks and white pines are the best climbing trees.

It seems to me that the underlined sentence is only a subordinate clause, which lacks the main clause? As they tell all (maple makes the best….
So I think it is an incorrectly written sentence.

Am I right?
