Jamie Graham of Tyngsboro, Massachusetts, just broke the New England Giant Pumpkin Growers Contest record for biggest pumpkin at the Topsfield Fair last Friday.    Graham lugged a whopping 2,480-pound pumpkin to Topsfield, knocking out the previous record holder by nearly 200 pounds!   He also won a cash prize of $8,522.  Graham’s kids named the gigantic gourd “Bear Swipe” because their dad has had problems with black bears clawing at his pumpkins.  The previous record holder was a 2,294-pound pumpkin, grown by Alex Noel of Abington, Connecticut.  Noel must have an affinity for growing giant pumpkins because he came in second place this year with a huge 2,234-pound pumpkin.
