Big day today, yes the Red Sox are in spring training, but that is not what I'm talking about.  Today is the day Sports Illustrated Swimsuit issue hits the stands!  What has by far become the most popular issue every year, SI does it again and once again Kate Upton graces the cover for the second year in a row!  The issue features 17 models and photo's from all seven continents.  One look at this teaser video and you will feel like you are in the middle of summer, and by the way the song from Train in the background isn't bad either!
