I just read this book and it's one that's hard to put down. The author is a geocacher. Much of the book is based in Austin, TX, but has areas from all around the country mentioned. Right now, it's only available on Kindle, but luckily, Amazon has apps for PC/MAC/iPad/iPod, etc...for free! Book is $10...but well worth the money.
Mark says that hopefully the book will be out in paperback some time soon. I have never read a book on my PC, so wasn't thrilled with the idea of doing it. I gave in, though as it's the only way to read this one right now. I was pleasantly surprised at how easy Kindle is to use, and found that reading on the PC isn't so bad...I do have a comfy desk chair!
Readers out there.....check it out.....but make sure you have some free time as you won't be able to put this book down!!
