While hunting in Mont. a couple of years ago during the second week of the season, we were speaking with the GW in the area and asked him about the hunt in the Tom Miner Basin area( just north of Gardiner) and he said that if we went there to not hunt alone and if we shot anything we'd have about 45 minutes to drag, clean and load the animal up before the bears would be there and that he had 5 hunters already that season run off from their kill due to the bears showing up and claiming the prize.
So with that said, the bears are enough of a risk that not a lot of hunters go to that area to avoid any run ins with the big guys.
There is a real need to have a season not just for the bears pop. but also the safety of humans weather hunting or not.
