Oregon resident Thad Starr will return to Half Moon Bay on Monday to defend his title in the Safeway World Championship Pumpkin Weigh-Off. Starr secured his victory last year with a 1,528-pound Atlantic Giant gourd. This year’s pumpkin weigh-off will begin at 7 a.m. at IDES Grounds, 735 Main St. Growers are competing for the title and a hefty share of about $20,000 in prize money. The winner will take away $6 per pound for the top pumpkin.
