Kahne, Johnson share joys of fatherhood

CONCORD, N.C. -- The latest NASCAR Sprint Cup Series off weekend fell on Father's Day weekend, and Kasey Kahne and Jimmie Johnson -- both dads themselves -- tweeted out their well wishes on the holiday.

Love this little boy to pieces. I wanna thank my dad for giving me all the opportunities I have had in my life. Love ya dad! #happyfathersday
