I know someone who churns credit cards systematically (you know, follows a regimen like suggested in the article) and has been traveling with his family around the world for years, taking trips every 4 to 6 weeks. That doesn't sound too "boring". In fact, we churned cards a few years ago to pay for our trip to Europe. We took our toddler. I would like to know where this "boring" life is that parents have. At times, I could use some of that.
