We put in at Harris on Sat. morning at daybreak and there was a boat tied up under the bridge. They had rigged a canvas to make a tent that covered the back, so I'm sure they were sleeping in there. Number of rodholders on side of boat, so I take it they were crappie fishing. Wasn't a pontoon, but it does take many people catching huge numbers to make a dent in the population. Let them spawn and catch them on the way back to deep water for the summer.
