I went up around van buren and didn't catch anything but a cat and a cold. Was very disappoints but the next day my uncle went down towards the dam and caught around 18 keepers. He said they just moved from tree to tree picking off 1 to 3 from each tree.
That's basically the way to do it right now you might catch 2 keepers on one tree and 8 on the next. You just gotta keep moving and not spend a lot of time in one place.
