I'd like to see North America become a dry, sunny, sandy region inhabited mainly by lizards, buzzards and a modest human population - about 25 million would be plenty - of pastoralists and prospectors (prospecting for truth), gathering once a year in the ruins of ancient, mysterious cities for great ceremonies of music, art, dance, poetry, joy, faith and renewal. That's my dream of the American future. Like most such dreams, it will probably come true. That is why I'm still an optimist.
