As for beverages, Washington was no stranger to alcohol, enjoying Madeira wine from Portugal, distilling his own whiskey, and enjoying a fruity brandy cocktail.
Washington was his own architect at Mount Vernon, "and he was very good at it," said Dennis Pogue, associate director for preservation at Mount Vernon. The piazza, which runs the length of the mansion, is "kind of California living in the 18th century," Pogue said.
The location, atop a sloping hill along the Potomac, catches cool breezes. Lots of windows and shutters allow for the regulation of sun and wind. And the distinctive cupola on the mansion roof serves as the mansion's air conditioning unit, funneling hot air out the top and drawing cooler air in at the ground level.
Visitors on Wednesday gathered on the mansion's back porch, a piazza overlooking the Potomac where breezes rolled through.
"It feels good out here. It's the same thing we do in Texas," said Chris Moore of Austin, sitting with his wife, Dina. The two had come to Virginia to see their son graduate from officer training at the Basic School at Quantico Marine Corps Base.
Moore said he opted for the smaller crowds at Mount Vernon as opposed to the massive Fourth of July Celebration on the National Mall because it afforded a better place to relax and contemplate the founding of the nation, especially since Mount Vernon on Wednesday hosted a naturalization ceremony for 100 new citizens from 47 countries.
"This place is incredible. It's just the kind of place that people need to see," he said, noting the divided nature of the country's current politics. "We all need to step back and look at where we started."
Up the river in Washington, President Obama also attended a naturalization ceremony at the White House, this one for active service members from 17 countries. Military families were invited for a barbecue and to watch fireworks on the South Lawn.
Obama said the varied backgrounds of those taking the oath typified America's long tradition of welcoming immigrants from around the world to its shores.
GOP presidential candidate Mitt Romney has spent most of the week off the campaign trail with his family in Wolfeboro, N.H., but took time Wednesday to march in the town's Fourth of July parade.
In New York, about a dozen disabled soldiers - most triple or quadruple amputees - visited ground zero ahead of the tourist throng. The visit was to salute service members who survived the post-9/11 wars to become miracles of modern medicine, and to promote two charities raising money for homes custom-built to ease their burdens.
On Coney Island, Joey Chestnut, 28, ate his way to a sixth straight win at the annual hot dog eating contest.
The city's celebration was being capped with the Macy's 4th of July Fireworks show off Manhattan.
