My best days have come in the heat of summer. Usually fishing standing timber in 12-20 fow with the crappie suspended anywhere from 4' down. I have found that the better ones are usually huggin the bottom. Just a note on winter fishing, when I was first starting to get into crappie fishing, a lady who was an avid crappie fisherperson (?) told me the best days are the ones that are so cold and bad that you have to convice yourself to go. I think that applies to summer time also, the hotter the better!
