Xbow,
My advice is get away from the roads and down in the big canyons for the best chance.
I know a few guys that have killed bears in the Book Cliffs without dogs or bait, just spot and stalk hunting.
But none of them were riding the roads when they did it. Go for a spring tag, find a canyon with water in it and NO ROADS, and go start glassing.
The strategy would be the same on the Lasals or the San Juan. Good luck, I know a few that have done it.
