Although we have not found many mistakes in the 1st edition of our book, we did find a few. Therefore, on March 19, 2015 we sent in some corrections. The 2nd edition of the book will be coming out soon, hopefully, with no mistakes at all. None of the mistakes changed any of the meaning of the book, but we will all feel better knowing that we did our best. Sandi, Ralph’s daughter, actually went back to the original letters and found a few words that I had interpreted wrong in the 1st edition (he was not always writing under ideal circumstances and some words were a little hard to read). So, if you have a 1st edition of the book, you will have a collector’s edition because the 2nd edition will be coming out soon.
