Trivial observation: There are more intelligent, broad-minded, and artistic people in a large city than in a small town, and more dwarves and unicycle riders as well. Which is exactly what you would expect for any trait or interest found at low levels in the general population. There is a large unicycle club in Minneapolis, but not in Little Falls. If you are wringing your hands over having no unicycle brethren, you should move to Minneapolis and join the club, and not waste time preaching the gospel of unicycles in Little Falls.
Lewis spends much time belaboring that incandescently obvious observation, supporting it with a cast of cardboard characters. That said, he does give powerful descriptions of the land and weather, and the book is readable if you just ignore his incessant harping on the obvious.
