I can relate. When I first converted from Bass to Crappie, i would launch my boat 30 minutes before daylight and fish through the heat of the day, and stay until the sun went down. More times than not, I would leave with just a handful of fish, if I was lucky! As the years have gone by, and my skills have improved(marginally!!) I consider leaving after 30 minutes without a bite! Can't hardly stand up straight after 3 hours in the chair!
