06/07/2011I did this many, many years ago. I am almost 50 years old and some of the thing that on this site I did growing up. I did the blind fold for an hour thing at a Girl Scout camp and did get a couple bruises but was not injured severely. I have done this with my own children and some of their friends when we would play \"Let\'s Pretend\" I tried to make it into a game and was able to teach them at the same time. I commend Mr Tulley for coming up with this book and school I just wish there was one in Texas. Good Luck with the book, camp and the school.
