I worked out how to harvest walnuts in season.
If there are no good winds, half of the nuts remain on the tree.
In order not to climb a tree, and not to shake, we tie a rope once between
two thick branches at the top. in the middle of this rope we tie another rope, the end
of which we lower down. Now it remains only to swing this end. Is it worthy of a patent?
