I went to the lake's that I have been getting limits(Michigan) in33-42 fow yesterday. Motored out to the spot i have been fishing and marked fish like crazy. Dropped down and couldn't get a single bite. The fish were everywhere and never got a bite for 2 hours. Finally caught a crappy. Ended up with 2 crappy and 2 gills. Released back in the lake. Something was going on, very unusual.
