There was an interesting short series of articles in the Washington Post Food and Home sections earlier this month on the possibility of transforming the South Lawn of the White House into a working farm, or at least creating a Victorian-style walled kitchen garden on the White House grounds.  That's the South Lawn on the cover of the wonderful Our White House: Looking in, Looking Out (Candlewick, 2008), which features at least one related entry:  "White House Colonial Kitchen Gardens" by Stephanie Loer, accompanied by S.D. Schindler's illustration of Thomas Jefferson taking a bite out of a tomato.  I love the idea of growing food at the White House (I suspect kids would, too) and am pleased that there are presidential precedents for it:  if you're interested, find out more at www.thewhofarm.org.  And even more about the White House in the book and at its companion site.  Welcome home!
