WINDSOR — The Windsor Fair, already Maine’s second-largest agricultural fair, will have more offerings than ever before when it opens Saturday, organizers said.

The fair is also scheduled to begin a day earlier, stretching the festivities to 10 days over two weekends.

The Windsor Fair has traditionally begun on a Sunday and continued through Labor Day, with the Union Fair previously wrapping up the Saturday before the start of the Windsor Fair. However, the Union Fair was moved this year to July, allowing the Windsor Fair to open earlier without the fairs interfering or competing with each other.

“We’re starting a day early, the first year we’ve had the full fair open that day, and there’s more people available on weekends, so we think it’ll work out well for us, we hope that will be a boost, though weather is always the big factor,” Tom Foster of Augusta, president of the fair for the past 32 years, said.

“We’ve got some real good entertainment lined up — great exhibits, a lot to see and do here. The place is probably the fullest it’s ever been, as far as vendors and farm animals and rides. Sizewise, and what we’ve got to offer, it’s as big as it has ever been.”

The fair typically draws about 100,000 attendees during its run. The fairgrounds is off Route 32 in Windsor, near the intersection with state Route 17.

First held in 1888, the Windsor Fair features an extensive range of agricultural events, including contests for animal showing and weight pulling, a midway from Rockwell Amusements and harness horse racing and wagering.

The fair is organized, run and staffed by about 225 people. Some of them are hired to work the fair, while many are volunteers who come back, often with other family members, year after year to maintain and improve the fairgrounds.

“We get at least 225 people that help put this thing on for us — it’s like a big family,” Foster said. “We all love being here, and we like one another, so it’s not only a job, it’s a lot of fun.”

Some new events this year aim to turn fair attendees into participants, including manure- and fry pan-throwing contests, farmers’ Olympics and a cornhole tournament, which are joining long-standing activities, such as beano games throughout the fair, contests involving cooking or pumpkin decorating, a pig scramble and the annual Windsor Fair Apple Queen Contest.

Events and entertainment are scheduled to include two automotive demolition derbies; truck and tractor pulls; fireworks; music by 12/OC, Chase Jobe Band & The Runnin’ Kind and Hurricane Mountain; magic; and freestyle motocross shows.

In a nod this year to modern technology, Wi-Fi has been added throughout the fairgrounds, according to Dan Foster, second vice president of the fair. Foster said Wi-Fi will be good for vendors who wish to take credit cards and provide internet connections to fairgoers.

Admission to the fair most days is $12 for those 12 or older, with those 11 or younger entering for free. Ride bracelets are $30.

On Monday and Thursday, admission for those 60 or older is $5.

On Wednesday, or “Half Price ‘Gate & Ride’ Day,” admission is $6 and ride bracelets are $15.

On Thursday, military veterans with identification receive free admission.

Individual tickets or ride bracelets can be used for the midway rides.
