A random thought, but if one were to conduct a census of all the, um, beings in Middle Earth, what would the final count be, about? LIke the number of elves, men, hobbits, dwarves and such. And how would one go about doing it?
Another thought, it seems like the main habitations of ME are the Shire, Rivendell, Gondor and Rohan. And nowhere else mentionable. Just remarking.
