THE weather was brilliant on Queen Street on Saturday.
More than 20,000 took advantage of the sunshine to attend the St Marys Spring Festival, regarded as the biggest event on the town's calendar.
Organisers from St Marys Development Committee were there from 6am to set up and were still in Queen Street 12 hours later.
Seven months of "full on" planning goes into making the event a success.
"Crowd numbers appeared to be down a little, possibly because of the federal election," president Tony Biddulph said.
"But everything went perfectly and everyone was well behaved. We've had lots of feedback from families who said they enjoyed the day."
There was something for everyone from Elvis and Johnny O'Keefe impersonators to amusement rides, laughing clowns, showbags, an animal farm and reptile demonstrations.
More than 200 stalls lined the streets.
There were 35 groups in the grand parade, ranging from Variety Bash cars to roller derby skaters, scout groups, dance troupes and bands.
"The parade is always the most popular event," Mr Biddulph said.
"People come from as far away as Wollongong and Dapto just to see the Bennett Wagon and horses leading the parade.
"People don't get to see it anywhere else."
Crowds flocked to the newly upgraded Coachmans Park, which reopened during the week.
A surprised Chris Miller was named St Marys Citizen of the Year on Thursday night in recognition of his tremendous work with St Marys Rotary.
"He's Mr Everywhere," Mr Biddulph said.
"People like that are very hard to find these days."
The St Marys Spring Festival will be back next year, amid talk it may be taken over by the St Marys Town Centre Corporation.
