I finally got around to reading Thoreau's Walden. Good book, but I can't believe they have high school kids reading it. The very beginning and the very end contain most of the philosophical bits, while the middle is a pleasant meditation on getting away from society and observing nature. With no discernible plot, I don't think this book would hold most people's attention.
Still, if you're in the mood for that sort of thing some winter's day, it is a worthy read.
