I do but it is tough in this area.We don't have any real berry crops so bears are scattered and there is a lot of big woods.There is a service berry patch that they hit about Oct 1 but no cover on the downwind side.
Choke cherries can be real good but most years,here,they are done before season starts.Some areas,that may not be the case.
In the Nortwestern part of the state there should be some blueberries and if they are still on when season starts,that may be the ticket.There aren't a lot of apple trees in Montana but if you could find a small orchard,you would be in business.
In the Fall it is all about the food sources and what is in,what week.The bears know where everything is and when to be there.They have a great memory for any place they ever got a meal.
Overall,I think it is tougher in the Fall but if you had good information on a great crop like blueberries and were sure you could time your trip with THIS years crop,you might do well.
Another food source that bears here love in the Fall is White Bark pine seeds.I think the White Bark pines are at higher elevations but honestly don't know a lot about them.Bears in the mountains often rely on them,late September and October.
As bears are frantically trying to put on pounds for the Winter,they grab every opportunity to get protein so predator calls work really well in the Fall but this may be better with 2 guys.Electronic calls aren't legal.You need to blow the call almost constantly for up to an hour and be ready to be bum-rushed at close range by a serious bear.
I would say if you decided to do the Fall hunt,get information on a good food source and confirm that it will be viable when you can come.Work the food source and bring a predator call to use as well.
In one of my best Spring areas,it is almost impossible to see a bear in the Fall.It is all about the food.
