Do you know what Lord of the Rings is missing? Flying Horses!!!!
Lord of the Rings has GMOd eagles GMOd bees, and superheroes that can shape shift from a bear to a human, but no flying horses. Frodo's journey would have been so much easier on the back of a Pegasus, because a flying horse can fly to areas that regular horses could not and hide on the ground when the Nazgul search for the ring when an eagle could not. Maybe that is why, the journey would be two easy for three books.
