As Americans gear up to celebrate the nation's birthday, here are some Fourth of July highlights from around the country:

IN AMERICA'S BIRTHPLACE: CONCERTS, A PARADE AND BEER

Philadelphia started its Fourth of July celebration a little early.

The city's Liberty Block Party kicked off the festivities Friday near Independence Hall with music on three stages, treats from local food trucks and restaurants and a beer garden.

The Philly Pops performed patriotic tunes Friday night on the Independence Hall steps.

Saturday's events include a Celebration of Freedom ceremony, a parade through the city's historic district and a free concert and fireworks on the Benjamin Franklin Parkway. The Celebration of Freedom marks the 50th anniversary of a protest outside Independence Hall that would be a milestone in the fight for gay rights.

The concert features performances from Philadelphia's own The Roots, Miguel and Jennifer Nettles.

NOTHING SAYS AMERICA LIKE MAPLE AND BACON

Fireworks, parades and a $17.76 maple bacon cronut sundae are on the menu for Nevada's Fourth of July.

The Reno Philharmonic Orchestra sets the soundtrack for the "Red, White and Tahoe Blue" fireworks show in Lake Tahoe. And parades in Fernley, Virginia City and Ely and Boulder City's "Damboree Celebration," build up to the main event.

For the 321,000 visitors to Las Vegas, the Fourth of July show on the Strip is set for Saturday night at Caesars Palace. Hungry? On-site restaurant Serendipity 3 is selling a maple bacon cronut sundae for $17.76.

If virtual fireworks are more appealing, the downtown Fremont Street Experience's video canopy offers displays every hour on Saturday night.

NATHAN'S HOT DOG EATING CONTEST

Competitive eaters have weighed in and are ready for Saturday's annual hot dog eating contest in New York at Coney Island's Nathan's Famous.

Four past winners hit the scales Friday and reigning champion Joey Chestnut is the heaviest at 230 pounds (104 kilograms). Repeat runner-up Tim Janus is at 165 pounds (75 kilograms).

Michelle Lesco is the lightest contestant at 112 pounds (51 kilograms) at the 99-year-old Independence Day boardwalk tradition while New Zealand native Nela Zissler is at 114 pounds (52 kilograms).

Chestnut broke a world record in 2013 when he ate 69 soggy dogs in just 10 minutes. He won last year's contest with 61 for his eighth victory.

Former champion Takeru Kobayashi is in this year's contest.

More than 30,000 are expected to witness the feeding frenzy.

SOME TROOPS OVERSEAS GETTING PIZZAS AS HOLIDAY TREAT

Hot dogs and burgers may be on the menu for many Americans celebrating the Fourth of July, but for some troops serving overseas, a different treat awaits -- pizza.

Pizzas4Patriots, an Elk Grove, Illinois-based group founded by a veteran, has arranged for 5,000 pies to be shipped to Afghanistan, and a thousand to Kuwait. Mark Evans, a retired Air Force master sergeant, says it's a way of giving back to service members.

Evans' group partners with businesses like Rich Products to make the pies and DHL to fly them. The pies are put on dry ice and driven to forward operating bases before being served.

Evans says Pizzas4Patriots has sent 150,000 pizzas to deployed troops for the Super Bowl and July Fourth over the past 8 years -- roughly a million slices. He says they also deliver pizzas to veterans' hospitals across the U.S.

BOSTON POPS FEATURE 42ND SHOW

Boston gospel singer Michelle Brooks-Thompson will perform the national anthem as Keith Lockhart celebrates his 20th year as conductor for the annual Boston Pops Fireworks Spectacular on Saturday.

The star-studded event is held at the DCR Hatch Cell in the city's Back Bay off the Charles River Esplanade and will also feature Broadway star Michael Cavanaugh, "American Idol" finalist Melinda Doolittle and "America's Got Talent" finalist Sons of Serendip, a quartet who met at Boston University.

Drum and bugle corps the Boston Crusaders and the USO Show Troupe will also perform.

A fireworks display will follow the concert.

Crowds came out Friday to listen to the performers rehearse.
