Fair season is the busiest of times for horsemen and women involved in harness racing. And if you’ve seen any races at the Cumberland County Fair, the Oxford County Fair or the Fryeburg Fair, there’s a fair chance you’ve seen at least one member of the Graffam family.

The Graffams operate Norton Farm in Falmouth, one of the oldest continuous working farms in the state.

Most of the horses are driven by Nick Graffam, 25, and trained by his father, Michael Graffam. Nick’s sister Bethany helps care for and train the 50 horses in the stables this year.

The fair season culminates this week in Fryeburg, with racing from Tuesday through Oct. 9 at 1:30 p.m. The Graffams will wrap up their season with the Breeders Stakes 3-year-old finals at Scarborough Downs on Oct. 15.
