A number of community bands, the Baltimore Ravens Marching Band, fife and drum groups and bagpipers also took part in Saturday's parade.
The region's businesses contributed floats, including Lancaster County, Pa.-based Turkey Hill with a giant cow float in honor of its ice cream and other dairy products, and the Legends of the Fog "haunted attraction" of Aberdeen, which featured a haunted cabin and people walking alongside it dressed in ghoulish costumes.
Sandra Raisin said she planned to attend the evening festivities as well.
"What could be better, food, friends and fireworks," she remarked.
Summer Tucker of Charlestown in Cecil County, her mother Jennifer and other friends and family gathered under a tent on the front lawn of a house in the 700 block of Union Avenue, a home owned by friends.
Summer Tucker said Saturday was her first time at the Havre de Grace parade since her childhood.
"It was good," she said as the parade wrapped up. "I like to see all the younger kids getting involved [in the parade]."
Tonya Buchanan of Elkton, a friend of Summer Tucker's, lauded the military members who took part.
"We're proud of the military out there," she said. "That's really nice."
Down in the park
As the sun crept lower in the sky, the crowds shifted toward Tydings park for the carnival, concert and fireworks, and they were joined by those who came for the night activities.
The carnival's Ferris wheel and other rides remained lit up and running as the colorful fireworks illuminated the night sky.
Every parking space that was available on grassy fields, business lots and side streets off of Revolution Street and Union was taken, and a number of people watched the fireworks from their balconies or yards.
Janae Hall, 18, of Abingdon, and her sister Janaya Allen, 13, said the carnival and fireworks were worth the trip.
"I love it," Hall said. "I love the colors; I love everything."
Janaya said Havre de Grace's celebration is "way bigger than any other" Independence Day celebration in Harford County.
Joe Boman of Baltimore, his fiance Melania Davis, sister Janae Dancy of Aberdeen and her 7-month-old son, DeMarcus, looked out over the carnival grounds after the fireworks.
"I come all the way out here from [Baltimore] to see the fireworks and the carnival," Boman said. "It's fun, come out, spend time with the family."
Dancy said she enjoyed rides such as the Street Fighter, which swung riders back and forth at dizzying angles.
"He liked the fireworks," she said of her son.
Davis called the fireworks "nice and loud and colorful."
Davis previously lived in Harford County and enjoyed the Havre de Grace Independence Day festivities.
"I just like that they have it every year," she said. "It's something nice for Harford County."
