I just really like Walden. The book is filled with beautiful ideas and is very much quotable. As for Belgium: there's not much nature left here. We have the Ardennes which is one of the last unspoilt areas in this country and every city has a park or two, but that's about it. We have places we refer to as 'forests', but whenever tourists venture there, well, let's just say they can't actually find the forest. They just find some trees and a muddy pond. Sad, really.
