Lindsay Crane was planning to celebrate her first anniversary with boyfriend Stephen Kenny last Monday in west Belfast, Northern Ireland, where they live. Little did she know, Stephen had something much bigger than a typical date night up his sleeve. Lindsay, who gave birth to the couple's first child together just a week before, opened a card from Stephen the morning of their anniversary, and she didn't just find the typical, "Happy anniversary, babe!" message inside. Instead, she found some money and two notes as well. One was the introduction to a scavenger hunt around the west Belfast area and the other was her first clue.
