Th Potholes (O'Sullivan ?) is a fun place. That lake has everything. Go back into the dunes and willows and you will find all the spiny ras you want. But actually my favorite lake for spiny rays is a little lake in sourthern Peirce County called Rap John. I take my float tube ouy there and catch many crappy, bass, blue gull and huge rainbows. All on the fly rod using wooly buggers.
