The same has happened to me. My best day to date was 3 hrs on December 11 in 2012. I fished from 7 til 10 and called a friend about a quarter of 9 and told him to get over here, it’s goin on. He did and had a bucket with him. I weighed 10 crappie that was just under 18lbs with a 2.2,2.4, and my pb at 2.6lbs in that group. I released all but 3 or 4 that wouldn’t revive and dropped them at some friends restaurant and went to work. My friend caught one or two of average size. The timing was that close. Like has been said, it may be different when you’re the first one there some morning.
Creativity is just intelligence fooling around
