What a wonderful idea. One of the coolest scenes in the movie Excalibur is Arthur and his knights in shining mail riding forth from the gates of Camelot, the sun begins to shine and the trees spring to bloom and flowers fall, to line their road to battle. It is perhaps the best of the Utopian ideals. And picking up from the wikipedia page the comment by author/historian Nancy J. Morris, in her book "The New Arthurian Encyclopedia, "Camelot, located no where in particular, can be anywhere."
Camelot is where all is as we would wish it to be.
Could not the world be as portrayed here in the painting God Speed by Edmund Blair Leighton?
