Siblings Clinton, 22, Emily, 18, and Brett Bippert, 20, ride the Breckenridge Park Train on June 4, 2012. From their mother, Frances Bippert: &quot;17 years [after taking a similar photo], this photo was taken on June 4, 2012, the same day Clinton was reporting to Navy boot camp in Illinois.  We wanted a family photo and decided to go back to Clinton's favorite place, that held such great memories.&quot; Photo: COURTESY
