New records were set in 2011 and 2012. The current world record holder is an Atlantic Giant pumpkin grown by Ron Wallace in September, 2012, which weighed 2009 pounds (911.3 kg). The 2011 record was by Jim and Kelsey Bryson, weighing 1818.5 pounds (824.9 kg).
Each year there is a new world's largest chosen, which may or may not exceed the existing record. It could be grown anywhere.
Generally they are grown in colder climates, with late freezes. Although soil type can override all of this: New Hampshire has had some massive gourds- weighing in at over 330 pounds.
