Tina, that was so much fun! You have a great gift for story telling and a fun imagination!
The mystery train made me think of the time my SIL and her boyfriend got tickets to sail on a "mystery cruise" ship. They got aboard and set sail only to find they got on the wrong ship and were with a bunch of Ford employees!! When word of their mistake got out they were treated like royality all night. Eventually they were able to straighten things and went on the "mystery' cruise and had fun there, too!
