The primary Easter Monday entertainment at the White House has always involved egg rolling. Participants roll dyed, hard-boiled eggs across the grass to see whose will go the furthest before cracking. Other egg sports enjoyed in the early years were egg ball, toss and catch, egg croquet and egg picking—a contest where eggs are pecked together until they crack. After a few days, the odor of all the eggs broken in these free-form games "could be smelled three square miles away."
