We had family pictures with the McBride's that morning. This was our last day of the trip home to NE (we were living in NC at the time). My family came out to "say goodbye" to us and showed up at the start of the pictures. Collin and I, along with all of our family, went out to the deck to take our picture. After a few normal pictures, Collin got down on one knee and asked me to marry him!
