The impact of controversial car parking charges introduced at Eaton Park on Saturday swiftly started to show.
At 9.10am on Sunday - a time when both car parks are usually busy - there was barely a vehicle in sight.
Helen Mitchell, chairwoman of the Friends of Eaton Park group said that the car parks had become "dangerously congested" and emphasised the environmental benefits.
"The response to the charges has been unduly negative," she explained.
"It's a gentle encouragement - not that gentle for some, I know - but I think the council has listened."

Season tickets cost £40 for six months and £70 a year - but are only valid for up to four hours a day. Blue badge holders can park for free.
The decision was made after a lengthy Norwich City Council consultation process, with a basic charge of £2 for four hours starting at midday on March 25.
"I think a minority of people will now not go," Helen added.
"Our city is rich in parklands and green spaces.
"Everyone in the city is within 15 minutes walk of somewhere.
"We need to find a sustainable way forward for the park - and driving short distances is not good for health or streets.
"It's important to encourage people to explore sustainable means of transport."

However, Gabriel Evbota - who chairs the Norwich and District Sunday Football League and Norfolk FA Inclusion Strategy Advisory Group - said the knock-on effects of the parking charges are already showing.
"It was rather empty this weekend," he said. "But the side streets were packed.
"We did say this would happen. Clubs are already looking to move their pitches.
"People just can't afford it. The cost is astronomical and really adds up.
"How many people will now be deterred from or deprived from using it?
"This is just one obstacle too many.
"The council seems to have shot itself in the foot."
