We had been watching this one for a while and decided to make a day of it in Dallas. It was a great time and a very welled placed "Trail". I learned more then I already had and can now understand why there still seems to be "questions". The only thing I did not like was the amount of people trying to sell "books" on what this Great Team put together. mad:. I guess that is all part of it. I want to thank the team for their time a dedication in putting this out there. It was a wonderful learning experience even for the little ones.
