I agree. And I still can't find anything on line about it. Which has me doubting it.
PA has had 800 lbs + bears. And 700lbs seems like every year here recently. Lots of 5 and 600pounders each season. So I suppose it is possible.
Limited hunting opportunities (no hounds, no baits) lots of food, and a perfect climate (cold enough to require body mass but not so cold that there isn't abundant food sources) let's bears live long and grow big.
