WASHINGTON -- The annual White House Easter Egg Roll has been rolling strong for 134 years. This year's version had an element of rolling thunder to it.

The No. 88 National Guard Chevrolet driven by Dale Earnhardt Jr. made a special appearance at The Ellipse in the nation's capital Monday, helping to kick off a patriotic initiative "NASCAR Unites -- An American Salute." The six-week program is designed to unify the NASCAR industry and fans in celebrating America and supporting military families.
