I know it may be a little lame.  Cheryl Strayed (“Wild”) did it on her trip along the PCT, but I would like to leave a new quote with my entries in trail registers along the trip.  I downloaded a pdf book, “The Great Book of the Best Quotes of All Time” to use as a source.  Click the image below to download the pdf; there’s also a link at the bottom of the page.

Learn from the mistakes of others. You can never live long enough to make them all yourself. – Groucho Marx
