One of recreational fisheries managers' biggest problems is that repeat buyers are not a very large component. Saw a paper a couple years ago and, if memory serves, it was something like 30% don't renew. Seems there is a base, which is probably where the harvest is, and lot of folks who try it and don't like it.

Plus, I think the majority of regular buyers are chronologically gifted and not being replaced.

That said, I think Doc's idea should be added for all of the mandatory report requirements. Big game tags, CRCs, crab, all of it.
