I ordered the old in fisherman Crappie wisdom book by Al Linder, I'm sure I will learn something new from it, I know it covers all the seasons, but I like to read in bed when I can't sleep. I see some other books but never heard of them before? The problem with most crappie books are they are from guys from the southern states, I don't care what anyone says our crappies up in the north don't respond the same way, and we don't have reservoirs we have natural lakes.
