Interesting. The National Park Foundation’s website just told me that the White House South Lawn is one of our country’s 392 national parks. Never knew that.

WASHINGTON — First Lady Michelle Obama is taking her campaign against childhood obesity to the annual White House Easter Egg Roll.

Besides rolling eggs with spoons, children will get a dose of activities to promote healthy living and exercise, including sports, dancing – and even yoga. White House chefs will be on hand to talk about eating right.

Performers at Monday’s event will include pop star Justin Bieber and the cast of the television show “Glee.” J.K. Rowling, the author of the “Harry Potter” books, and Olympic speed skater Apolo Ohno will also attend.

The Easter Egg Roll is the largest public event held at the White House each year, with 30,000 people from all 50 states set to attend.
