Trees and brush sure. And a tick can definitely climb a tree. But dropping down isn't the way they generally attach. They hold onto grass and low branches waiting for animals to brush past them. They don't really have a mechanism to alert them to the presence of animals walking below them fast enough for this to be practical for them.
