Venice Beach, Los Angeles.
The bohemian 'burb where seminal rock band The Doors lit their fire in the 1960s. Home to the bodybuilding boardwalk where Arnold Schwarzenegger began lifting his way towards superstardom in the 1970s.
It is an area which has always been seen as radical and unruly.
Now, nestled next to the Arnie-inspired weightlifters at Muscle Beach, among the thrift shops from where whiffs of incense and weed drift over, it is one of the places where you can often see the sporting craze creating a stir across the United States.
Pickleball.
Long seen as a leisurely recreation for older people, this hybrid of racquet sports boomed during the coronavirus pandemic and is the latest string-sibling to emerge from tennis' shadow.
Pickleball is the fastest-growing sporting activity in the US and the scenes of busy courts at Venice Beach - which have been predominantly used since the 1960s for paddle, another short-form game adapted from tennis - are being replicated across the nation.
"The tennis court is way too big and there's way too much ground to cover," says former Wimbledon junior champion Noah Rubin, who has switched from tennis' ATP Tour to take "a deep dive" into pickleball.
"I came across the pickleball court and, like so many others across the States, it clicked for me."
Combining elements of tennis, badminton and ping-pong, pickleball is played on a badminton-sized open court and with a lower net than tennis.
Players use solid paddles to hit a perforated and hollow ball, with the physics of the equipment limiting them to how hard and far they can whack it.
The smaller court means there is less running and more emphasis on hand skills.
One of pickleball's main marketing strands is stressing its fun and social benefits.
"You can play anywhere, you just need to throw down lines. It's a sport a nine-year-old can play or a 99-year-old can play," Rubin tells BBC Sport.
"There is nothing else like it. Pickleball is the most effortlessly accessible sport I've ever seen."
Almost five million people in the US played pickleball in 2021, according to research by the Sports and Fitness Industry Association (SFIA).
Over the past five years, the SFIA calculates the number of players has had an annual average growth of 11.5%.
Tennis, which has about 22.6 million players in the US, has seen an annual average growth of 4.9%.
"It is almost a cliche at this point that the pandemic did not so much create trends as much as accelerated them," says Tom Cove, president of the SFIA.
"Pickleball has grown in popularity for the past five years and did not miss a beat during the pandemic.
"Pickleball's growth trajectory gives every indication it will be a significant part of the American sport landscape for the foreseeable future."
From Eva Longoria to LeBron James - tapping into the power of celebrity
Pickleball is not just growing rapidly as a participation sport.
Tapping into the power of celebrity and using smart social media strategies have been key in growing it as a consumer sport.
The biggest, richest and most high-profile professional league - Major League Pickleball (MLP) - has been expanded to 24 teams and many are backed by A-list ownership groups.
Four-time Grand Slam tennis champion Naomi Osaka and Wimbledon runner-up Nick Kyrgios have invested in a new Miami-based team alongside NFL superstar Patrick Mahomes.
Another expansion consortium includes legendary NFL quarterback Tom Brady and four-time tennis major champion Kim Clijsters, while basketball superstars LeBron James and Kevin Durant, plus actress Eva Longoria and supermodel Heidi Klum, are also putting in money.
There will be six events across the US for the mixed-gender teams and the prize money pot has increased to $5m (£4.1m).
The commercial growth is also enticing professional tennis players to switch over.
Recently retired American Sam Querrey, who notably beat Andy Murray to reach the 2017 Wimbledon semi-finals, is the biggest-name convert and will play in the 2023 MLP.
