From the official White House blog:
Are you in? Don't miss your chance to join the First Family for the 135th annual White House Easter Egg Roll on Monday April 1. This year's theme is “Be Healthy, Be Active, Be You” -- and more than 35,000 people will be joining the First Family on the South Lawn for activities including games, stories, singing, dancing, and of course, the traditional egg roll.
Once again, tickets will be distributed through an online lottery system, allowing guests from across the United States to participate in a tradition that dates back to 1878. Starting today, you can click here to enter the lottery and win a chance to join the fun (the lottery closes at 10 am EST on Monday February 25, 2013). The event is open to children aged 13 years and younger and their families.
In addition to all the fun and games, the day's activities -- which will include sports and cooking demonstrations -- will help educate families on smart ways to incorporate healthy eating and exercise choices into their daily routines, which are key pillars of First Lady Michelle Obama’s Let’s Move! initiative.
Families and schools who can't make the trip to Washington, DC but want to participate in the festivities can enter the annual poster contest.
