SPRING is in the air in St Marys.
Crowds will come out of hibernation this Saturday with a spring in their step for the St Marys Spring Festival in Queen Street.
Now in its 38th year, it's St Marys' biggest day of the year, attracting visitors from across Sydney and beyond.
St Marys Development Committee hopes the fine weather will continue.
"It will be the best event yet," president Tony Biddulph said.
Queen Street will be closed to traffic as 215 stalls line the pavements.
Organisers promise something for the whole family from entertainment and showbags to amusement rides, car displays, reptile demonstrations, pony rides and an animal farm.
The regular Elvis and Johnny O'Keefe impersonators are back while the shooting gallery, giant slide and spinning teacups are always crowd pleasers.
There aren't any big acts from Sony coming to perform like in recent years.
But cricket fans may remember former Test bowler Len Pascoe, who will be in St Marys on Saturday and be part of a Q and A session in the newly reopened Coachmans Park around noon.
A must-see attraction is the grand parade at 12.30pm, led by horses and a Bennett wagon, which made St Marys famous in its early years.
Float numbers for the parade are down but are expected to pick up this week.
"You won't see a Bennett wagon anywhere else," Mr Biddulph said.
"We were talking with a family who came from Wollongong last year who said it was the best thing they'd ever seen."
Secretary/treasurer Norma Thorburn said the day is equivalent to the Royal Easter Show for some families.
"It's a great but not expensive day out," she said. "I encourage people to come along and see what St Marys has to offer. It's the best day of the year for our town."
Festivities start Thursday night, when organisers crown the St Marys Citizen of the Year, who will be part of the parade.
In his many years on the committee, Mr Biddulph has never see the grand parade.
"I'm hoping to get someone to video it," he said.
Fusion Western Sydney is getting in the spirit of the festival.
It will have a stall in Queen Street and a large and colourful procession in the grand parade, where it hopes to defend its best walking group title.
The Fusion "Chicken" is back by popular demand for the parade, to be joined by participants from the drumbeat, dance and Golden Days ballroom dancing programs.
