What tag did she get?
There are some good bulls down there but they are a little skippy because all the bow hunters that hunted cows/spikes on there for the last month ran them to death.
Try Red Desert, Tippets Valley area. Anywhere public around the lake is great for the rifle...then they go lower if it snows. Most big ones come off down toward Panguitch later on. Go ask some of the local boys, they will know where to point you.
