Maybe we need to send some of our NM wolves up to the poor guys in Idaho, they're doing population control hunts here. The few grey wolves they introduced don't seem to be making the promised dent.
As for the "50 elk per year per wolf" number, that's 20-30 lbs of meat per day for each wolf. I don't think they'd be running down that many elk with their belly dragging on the ground. 50 elk per pack sounds more reasonable.
F 135 - the right choice
