I just started this book, and I can just tell it's going to be good. I'm only mentioning it because it seems to be free to download today. It's about this funny couple (the lady is terrified of rodents, which to her includes squirrels, marmots, and chipmunks) who travel to all of our great nation's national parks.
I would recommend downloading it today. If you don't have a kindle, but you have a smart phone, you can always read these things on your phone.
