I don't think a size limit would work. For one, the CO's are spread too thin to enforce the laws we have. We end up policing each other many times when we see a law broken and call it in. Who wants to go up to someone and say we want to measure their fish to make sure they are legal and then call in violations. I don't think there is a magic pill for this issue. I have to admit I have kept 7" and 8" crappie before. I don't fill my cooler with them though. I also release any bass, either smallie or LM. We have to do what we think is right and try to educate the rest as much as we can. How we do that is the tough part. I respect all others views and ideas and hope everyone does likewise.
