I grew up with a wood burner for heat in the winter, so ever summer we'd go out and cut down a dead tree somewhere, cut into chunks that can be rolled or carried to a truck bed, hauled home, unloaded, and repeated until the entire tree was collected. That would mean probably 5-10 truck loads in a standard farm truck. With 3 non professionals running 2 chainsaws, that's 4+ hours not including drive time.

So while this is satire, for anyone who's not cut down a tree before, especially one with consequences if you fell it wrong, the pros make it look fast an easy.
