It's a book of philosophical meandering ramblings about walking and sailing old routes. It starts out with a great deal of meandering musings, but if you can get past that, there are some interesting discussions of old footpaths and sailing routes. And there are also some thoughts about artists which I found hard to take. I'm glad I read this book, but I wish I'd been more confident about skimming the parts that I didn't like. The sailing routes are interesting, giving some notion of how folks navigated before they had accurate clocks and such. There are ancient footpaths that intertwingle with modern routes; others that are submerged at high tide. There are some pretty interesting parts sprinkled through this book.
