WASHINTGON -- See Michelle Obama's famous vegetable garden up close this weekend.
The White House is opening its grounds to visitors on Saturday and Sunday for the twice-annual White House Garden Tours.
The South Lawn of the White House will also be open to visitors. It's home to the enormous -- and recently replanted -- Kitchen Garden. It's also one of First Pet Bo Obama's favorite places to play, so look out for chew toys.
