From fireworks soaring above the Washington Monument to hot dogs being downed in New York City's famed frank-eating contest, Americans aren't shy about celebrating their nation's birthday. Many places are rolling out long-established Independence Day traditions on Monday (even if some of those traditions aren't as long-established as they sound). Rain was forecast in many cities, but revelers were trying not to let it dampen their fun. Some Fourth of July highlights from around the country:
INCREASED SECURITY FOR NEW YORK CITY'S FIREWORKS SHOW
Police have dispatched 5,000 officers to oversee the Macy's Fourth of July fireworks display in the nation's largest city. That's the largest detail the New York Police Department has ever assigned on July Fourth.
Authorities say there are no known, credible threats against New York but vowed to remain vigilant as more than 1 million spectators gather to view Macy's annual fireworks display over the East River.
Chief of Department Jim O'Neill told reporters Monday there will be officers equipped with heavy vests, helmets and carrying rifles at each of the 24 entry points to see the show on Manhattan's east side.
More than 30 police dogs will be on patrol as well as every NYPD boat from the marine unit, O'Neill said.
"The world has changed," he said at a briefing for a new counterterror unit deployed for its first July Fourth. "This is the standard package, and we'll add and subtract as we see necessary."
COOL, RAINY WEATHER DAMPENS JULY FOURTH IN THE NATION'S CAPITAL
Unseasonably cool, rainy weather has dampened the festivities along the National Mall in Washington, D.C.
Just hours before the massive fireworks display in the nation's capital Monday, only a handful of people were picnicking in tents or under makeshift shelters. Others headed for the museum.
But as vendors hawked ponchos and umbrellas, some of the faithful fireworks fans said they would brave the elements no matter how rainy it got.
"We're not going anywhere," vowed Heather Wright, of Columbus, Ohio, as she camped under a tent with her husband, their 9-year-old son and their 10-year-old nephew.
IN THE NATION'S BIRTHPLACE, A PARADE AND A PARKWAY PARTY
In Philadelphia — where the Founding Fathers approved the Declaration of Independence on July 4, 1776 — the national birthday party runs all day.
It kicks off at 10 a.m. with a reading of the document and an event honoring everyday heroes, with celebrity guest Leslie Odom Jr., a Philadelphia native who plays Aaron Burr in the Broadway musical "Hamilton." Then comes the holiday parade, which includes Miss America 2016 Betty Cantrell.
Next up is a five-hour party with free entertainment on the Benjamin Franklin Parkway. The celebration continues with a five-hour concert with performers including Odom and singer-songwriter Leon Bridges. Fireworks close out the day.
A FINAL WHITE HOUSE FOURTH FOR THE PRESIDENT
It's the last Fourth of July at the White House for President Barack Obama and his family, and they're having some people over: military families and two of the president's favorite performers, singer-songwriter Janelle Monae and rapper Kendrick Lamar.
The Democratic president and his wife, Michelle, invite military families each year for a barbecue, concert and view of the fireworks on the National Mall.
For a second straight year, rainy weather forced the cancellation of the annual Fourth of July picnic and fireworks watch at the White House. Lamar and Monae will perform indoors, in the East Room.
NEW YORK: FRANKS AND FIREWORKS
American as apple pie? Fuhgeddaboudit. The frankfurter rules the Fourth in New York City, where the annual Nathan's Famous hot dog eating contest marks its centennial this year — well, not really. Nathan's itself dates to 1916, but showmen behind the hot dog competition have acknowledged they made up a long-told story about the contest beginning that year, too. It actually started in the 1970s.
Joey "Jaws" Chestnut beat his own record Monday when he polished off 70 hot dogs and buns in 10 minutes. He also regained his title after losing the Mustard Yellow International Belt to Matt "The Megatoad" Stonie in 2015. "Last year was rough," Chestnut told the crowd. "This year was the best ever."
Later Monday, Macy's is promising its biggest Fourth of July fireworks display since the millennium show of 2000. The show features more than 56,000 pyrotechnic shells, 22 hues and the New York debut of "pyro-writing" in the sky, all synchronized to patriotic tunes performed by the United States Air Force Band. Country singer Kenny Chesney, pop band 5 Seconds of Summer and pop singer Meghan Trainor are among the performers.
Hundreds of thousands of people are expected to line the banks of Boston's Charles River to watch the fireworks there, with millions more across the country watching live on CBS.
The celebration features pop stars Nick Jonas and Demi Lovato, country group Little Big Town and, as always, the Boston Pops Orchestra, which drives home the climactic fireworks finale to Tchaikovsky's "1812 Overture."
JULY FOURTH, CALIFORNIA-STYLE
There's a something-for-everyone approach to fireworks in Los Angeles, where displays are planned at the Los Angeles Memorial Coliseum, the Hollywood Bowl, Grand Park near City Hall and the Rose Bowl in Pasadena, among other places around the massive metro area. San Francisco holds a large fireworks display over the San Francisco Bay.
IN OKLAHOMA, A PARTY TO COMMEMORATE THE NATION'S BIRTHDAY
About 80,000 people are expected to gather Monday night in Tulsa, Oklahoma, to celebrate the nation's birthday and the reopening of the River West Festival Park along the Arkansas River. Revelers at 2016 Folds of Honor FreedomFest will enjoy food trucks, inflatable rides, games and live music as fireworks choreographed to patriotic music fire off in the background.
NATION'S OLDEST ONGOING JULY FOURTH PARTY
A seaside town in Rhode Island hosted what's known as the nation's oldest continuous Fourth of July celebration, with 19 marching bands and 17 floats making their way through the streets of Bristol on Monday. About 100,000 people turn out for the parade in a typical year, according to city officials. An Independence Day celebration has taken place in Bristol since 1785, and the event has become entwined with the town's identity, WPRI-TV reported. A red, white and blue center stripe runs down the town's main street, and real estate listings for houses often note if they are on or near the parade route.
