Yeah, there are flaws in the farm country bears v woods bears theory. The Pocono Mt area which certainly is not farm country produces some of the biggest black bears in the country, the in excess of 800 lbs bear that is now on Display at the Hamburg Cabelas store was killed in Lycoming county. Is it easier for a bear to find a free meal around a farm, sure once the crops are producing grain, however before that they eat what the wild land provides and the fact that they will eat pretty much anything, plant or animal gives them the opportunity to put on fat. Just like deer, age is a huge factor in very large bears, they must live long enough to get very large. There have been studies done and the biologists believe there is something in the genetic make up of PA bears that allows them to get so large with age and also allows them to be more prolific than most black bears, triplet cubs are not uncommon in PA.
