Try this;
Drive to Ovando which is on Hiway 200 a couple hours NE of Missoula.
Stop at Trixies Tavern, neat place, and get a burger.
Then drive 10 miles NE along the Cooper/Blackfoot Road to a camping type area with a bunch of horse pens.
Spend the night there and then head up the FS trail along the N.F. Blackfoot about 6-7 miles.
There an old FS cabin there.
This is by a wider basin where we saw quite a few decent bucks 10 years ago.
We saw more deer to the left (North).
There was an unused oufitters camp to the northeast of the cabin about 1.5 miles so I imigine it got a little pressure.
This late in the year I think that the deer are moving down so it would be a transitional population of deer.
I can't imagine things have changed that much for deer.
We were after elk so we passed on the bucks.
Good Luck,
Rob.
