Becky Carey always imagined her dad would walk her down the aisle. Although he had been battling pancreatic and prostate cancer since 2014, she hoped he would be there for her big day. But when Tim Carey's health took a turn for the worse, Becky decided they would still have their moment together - sharing a "practice" dance in the backyard. Her dad donned his Air Force uniform and she put on her wedding dress. Instead of an engagement photo shoot with her fiance, she took these moving photos with her dad. And then the two danced to Tim's favorite song, "Unchained Melody."
