I mentioned before that Beth and I were two opinionated women traveling together. The reason it works is that 9 times out of ten we are of the same opinion! We went on the self guided Nature Walk and it was very interesting. We drove through the Park, looked at each other and said, let's get out of here. Frankly, you've seen one Dune you've seen them all!The sky was very stormy with storm cells all over.
