A hazy sky hung over downtown Palos Heights on Thursday evening as smoke from the Canadian wildfires drifted across the Chicago area, but it did little to keep car enthusiasts from enjoying one of the city’s favorite summer traditions.

Hundreds of classic automobiles lined Harlem Avenue between 122nd and 125th streets for the annual Palos Heights Classic Car Show, drawing a steady stream of visitors eager to admire vintage vehicles, listen to live music and enjoy a summer evening in the heart of the city.

The show featured vehicles spanning nearly six decades, from elegant automobiles of the 1920s to gleaming muscle cars and iconic cruisers from the 1980s. Owners spent the evening chatting with visitors, many of whom stopped to ask about the history behind the meticulously restored cars.

Dan Watson, of Tinley Park, displayed his 1966 Ford Mustang, a classic he has owned for 26 years.

Nearby, Dan Wodrich, of Homer Glen, showcased his 1993 Chevrolet Corvette, which he purchased in 1998.

David Valdez, of Justice, brought his 1971 Chevelle SS, a familiar sight at the annual gathering.

“I’ve been coming to this car show every year for the past 10 years,” Valdez said.

Greg Urdal, of Palos Heights, displayed his distinctive 1966 Chevy II station wagon, a vehicle with deep family roots.

“This was my dad’s car,” Urdal said. “I sold my race car when my son, Grant, was born and figured it was time for a family car.”

Despite the smoky, gray conditions that gave the evening an unusual appearance, families filled the streets, stopping to photograph their favorite cars, catch up with friends and admire the long rows of polished chrome and colorful paint.

Live music echoed through downtown as visitors wandered from one end of the show to the other. Local restaurants and vendors stayed busy serving food and beverages while attendees lingered well into the evening, swapping stories and reminiscing about the vehicles they once owned, or wished they had.

The annual event once again proved why it has become one of the south suburbs’ signature summer traditions, bringing together generations of car lovers for an evening built on nostalgia, craftsmanship and community.
