That struck me, too. Two is the normal litter for bears. I know a guy who killed a female bear in the early spring in northern Maine. (He was bear hunting and sat down to rest in a clearing, when a she-bear appeared on the other side of the clearing. She rose on her rear legs and began to roar, apparently intending to scare him. It worked. He shot her. Given her sex and the time of year, she probably left two cubs somewhere in the forest. Momma got a ride back to Massachusetts down the Maine Turnpike on the roof of an International Harvester 4WD small truck, to the horror and affliction of sensitive out-of-staters. This was before the days of the SUV. You had Jeep and you had IH.
So what Native Indian land was he hunting?
