Yes it's true, my parents got married on February 29th, 44 years ago today. We always joke with them that they did it that way because my dad was too cheap to buy an anniversary gift and only wanted to do it every 4 years! But the truth is that my dad was going to be drafted, so they had to push their wedding up, and February 29th was the only day the church was available.
Another on-going joke in our family is that they've only been married for the number of "real anniversaries" they've had. So today, we joke that it's only their 11th anniversary! Hahaa!! Happy anniversary to my parents!!
