An adventurous boyfriend pulled off an incredible underwater proposal while vacationing in the Dominican Republic. Travis Grenier and Kenna Seitz were 30 feet deep when he popped the question. On the sand below the couple was a tiny treasure box. Seitz was shocked to find an engagement ring inside. It was a picture-perfect scene as colorful fish swam around them in the blue water. The couple hugged, and Grenier threw his hands up in joy.
