Where are the bison, we are at south pasture

Sometimes they are laying in the tall grass and hard to see.

There's a small pond or watering hole on the very South end of the pasture, I've seen them there a few times.

Sometimes you have to drive around the outside

We saw them while driving from the road. They were grazing near the fence.

They wander around and are a bit skiddish with people. I saw them near the trail
