I learned about Thoreau's birthday in this article in the Sunday New York Times Magazine.
I've never gone off to live in the wilderness. I only went camping once. But I love hiking on trails, in parks and in preserves. I snatch what little pieces of nature that I can; I find it peaceful and meditative to walk in those pieces of nature.
After I read the essay, I realized that I haven't read Walden. I vaguely remember reading an essay or two, but not the complete work.
Then I remembered that we have this copy of Walden. I checked the bookshelf and also found this book by Thoreau.
I've got my next two books to read lined up.
