Birthday girl
Title:  Birthday girl
Description:  My wife(she wasnt yet in this photo) was adventurous, so when I suggested we take a ride behind a steam engine, she was all for it. She posed with one of the drivers on UP 4012 here, four days after her birthday, showing how big they are. She had a good time that day, and would do it again.
